Babies have shorter sleep cycles than adults and spend more time in light sleep, which means they are more likely to cry, make noises, or move in their sleep. Crying before sleep is usually not a cause for concern, but it can be distressing for parents. If your 3-month-old is crying before sleep, it could be due to various reasons such as hunger, discomfort, or separation anxiety. Establishing a consistent bedtime routine can help reduce crying at bedtime, and it is important to ensure that the sleep environment is comfortable, with the ideal temperature between 68°F and 72°F. Some parents may choose to use sleep training methods such as the cry-it-out approach, but it is recommended to wait until babies are at least 16 weeks old before starting sleep training.

What You'll Learn

Babies may cry due to hunger or discomfort
A 3-month-old baby crying before sleep could be due to several reasons, including hunger or discomfort.
Hunger
Babies instinctively cry to communicate hunger. In the first few months, it is expected that babies will wake up multiple times overnight to feed and stay hydrated. They may cry out in their sleep to signal to caregivers that they are hungry. If your baby has not eaten in a while, offer a quick feed before settling them to sleep.
Discomfort
Babies may also cry before sleep due to discomfort. Discomfort can be caused by various factors, such as teething pain, a cold or flu, or eczema. For example, if your baby has mucus or blood in their stool, their tummy may be irritated, causing discomfort. Additionally, ensure the room temperature is comfortable for the baby. Experts recommend a sleep temperature between 68°F and 72°F (20°C to 22°C). Dressing babies in heavy layers is not advised as it can cause overheating.
If your baby is experiencing discomfort, it is important to address the underlying cause. For instance, if your baby has eczema, consult your healthcare provider for advice on managing the condition.
Other Possible Reasons
Apart from hunger and discomfort, babies may cry before sleep due to pain or medical issues such as an ear infection or reflux. Separation anxiety or emotional distress may also disrupt sleep temporarily.
If you suspect your baby is crying due to pain or a medical issue, consult your healthcare provider for advice and treatment.

They may be too hot or cold
It is entirely normal for babies to occasionally cry in their sleep. However, if your 3-month-old baby is crying before sleep, they may be too hot or cold.
Babies have shorter sleep cycles than adults, spending more time in light sleep, which means there are more chances for them to cry, make noises, or move around in their sleep. Light sleep is also known as rapid eye movement (REM) sleep, during which your baby dreams. You might notice their eyes moving behind their eyelids, or that they jerk or twitch. Their breathing may also become irregular.
If your baby is crying before sleep, it could be that they are too hot or cold. Experts recommend setting the temperature between 68°F and 72°F (20°C and 22°C) and advise against dressing young babies in heavy layers. As a rule of thumb, whatever you are wearing plus one layer is sufficient, for example, a long-sleeved sleeper and a sleep sack.
If your baby is crying before sleep, it could be worth doing a quick check of their sleep environment. Ensure the room is dark, as babies often struggle to wind down for sleep if there is too much visual stimulation. They may hyper-focus on an object or the light coming in around the blinds and become upset. A dark, boring bedroom is best for sleep.
If your baby is crying before sleep, it could be that they are too cold. If this is the case, you may want to add an extra layer to their sleepwear, such as a sleep sack. However, be mindful of overbundling, as this can also make your baby too hot.

They could be in pain
It is normal for babies to cry before sleep or during sleep, and there could be several reasons for this. One reason could be that they are in pain or discomfort. Babies could be experiencing teething pain, or discomfort from a cold or flu. In addition, babies could be signalling that they are hungry or that they need a diaper change.
If your baby is crying before sleep, it is important to first rule out hunger and check if they need a diaper change. If this is not the case, then the next step is to check their sleep environment. The room could be too hot or too cold, which may be causing discomfort. Experts recommend setting the temperature between 68°F and 72°F (20°C and 22°C) for a comfortable sleep. It is also advised to avoid dressing young babies in heavy layers.
If your baby is still crying, they could be experiencing pain or discomfort due to other reasons. For example, they might have mucous or blood in their poo, or their poo could be frothy or runny, indicating a sore or irritated tummy. Eczema or dry, rough skin can also cause discomfort and interrupt sleep. In such cases, it is important to consult a doctor or paediatrician for advice and treatment.
It is important to note that occasional crying before sleep is usually normal and not a cause for concern. However, if the crying persists or occurs in longer bursts, it is recommended to seek advice from a healthcare professional. Persistent crying may also be a sign of a more serious illness, such as an ear infection, and medical attention should be sought if this is suspected.

They may be experiencing separation anxiety
Separation anxiety is a normal phase of development that usually kicks in around 7 to 8 months old, peaks at around 18 months old, and can continue into toddlerhood, though often with less intensity. It can even occur as early as 4 months. Separation anxiety can impact all aspects of your child's life, including sleep. Your baby may be experiencing separation anxiety if they become nervous whenever they lose sight of you or another trusted caregiver and are left with someone unknown or unfamiliar. The most noticeable signs of separation anxiety in babies are increased clinginess and crying, especially when you are initiating the separation—for example, when you put your baby down or leave the room.
You may see new or more frequent sleep struggles from separation anxiety, such as night wakings. Separation anxiety can cause temporary disruptions to your baby's sleep since their body is likely to be on higher alert than usual during this period. However, this disruption should be short-lived, around one to two weeks, if you remain consistent with sleep schedules and bedtime routines.
If your baby is experiencing separation anxiety, you can help them by providing a lovey or comfort object. Loveys and comfort objects can be a great help during surges of separation anxiety, but be sure to wait until your child is at least 12 months old before allowing one in their crib.
It's important to remember that every baby is unique and develops at their own pace. If you have concerns about your baby's crying or sleep habits, consult your paediatrician or a healthcare professional for personalized advice and guidance.

It could be a sign of a more serious illness
While crying before sleep is common among 3-month-old babies, it could sometimes be a sign of a more serious illness. Crying in sleep may be due to pain or discomfort from teething, a cold, flu, or food sensitivities. Persistent crying may indicate a more severe condition, such as an ear infection or other medical issues. If your baby is crying due to illness, you may notice additional symptoms such as mucus or blood in their stool, a sore or irritated tummy, or skin irritation from eczema.
If you suspect your baby is crying due to illness or medical issues, it is important to consult a doctor. Before seeking medical advice, there are a few initial steps you can take to soothe your baby and improve their sleep environment. Ensure your baby is not crying due to hunger or a need for a diaper change. Check that the room temperature is comfortable for your baby, ideally between 68°F and 72°F (20°C and 22°C). Reduce visual stimulation in the room by creating a dark and boring environment to help your baby wind down.
If your baby continues to cry with intensity, try to soothe them by repeating the final steps of your bedtime routine. You can also stay in the room as your baby falls asleep, gradually working on leaving once their anxiety has subsided, which may take weeks or months. It is important to be consistent with your approach and stick to the same type of reassurance to help your baby understand what to expect and reduce their crying.
If your baby's crying persists or you suspect they are in pain or discomfort, it is crucial to seek medical attention. Your doctor can help identify the source of the problem and provide guidance on improving your baby's sleep and overall well-being.
