Sleep regression can be caused by a variety of factors, including separation anxiety, nightmares or night terrors, teething, sickness, and changes in daily routine. Establishing a consistent sleep schedule and addressing any underlying physical or developmental issues can help improve sleep patterns in toddlers. While most toddlers will grow out of this phase, it can be challenging for caregivers, requiring patience and understanding.

What You'll Learn

Sleep regression
At 18 months, toddlers are well into the toddler stage of development, marked by rapid changes in their physical abilities, cognitive skills, and emotional evolution. Their increased mobility, awareness, and communication skills can all contribute to sleep regression. It is important for parents to maintain healthy sleep habits during this time, such as reinforcing bedtime routines and sleep schedules, creating a comfortable sleep environment, and providing comfort and reassurance.
To improve sleep during the 18-month sleep regression, it is recommended to offer an age-appropriate bedtime, prioritize naps, and consistently enforce bedtime routines. During their awake time, 18-month-olds need active play to get their bodies moving and tire them out before sleep. Allowing for a full wake window before sleep will help your toddler fall asleep and stay asleep.
It is important to remember that every child is unique, and sleep regressions can vary in duration and intensity. While challenging, sleep regression is typically short-lived and temporary, resolving as the child gets older.

Separation anxiety
At this age, toddlers are gaining mobility and becoming more communicative, which can deepen their emotional reactions and increase separation anxiety. They are also developing their thinking, reasoning, and cognitive functions, which can contribute to their anxiety.
The most common signs of separation anxiety in toddlers include increased clinginess and crying, especially when you are initiating the separation, such as when putting them down or leaving the room. You may also notice new or more frequent sleep struggles, such as crying out during the night or struggling to fall asleep.
To help your 18-month-old with separation anxiety, you can try the following strategies:
- Create gradual distance: If your toddler cries, try to soothe them from a little farther away each time.
- Provide comforting accessories: Allow your toddler to have a favourite toy or a comfort object, such as a lovey, to remind them of you and provide reassurance. Ensure these items are safe and not choking hazards.
- Practice incremental separation: Do separation trial-runs during the day so your toddler gets used to being with other adults and can learn to stay calm when you are not by their side.
- Encourage self-soothing: Avoid immediately responding when your toddler cries. Give them a chance to calm themselves before tending to them.
- Avoid co-sleeping: Help your toddler feel more independent and secure in their own bed by avoiding bringing them into your bed.
- Establish a sleep schedule: A regular sleep schedule for both nighttime sleep and naps can reinforce a positive sleep pattern.
- Make their sleep space comfortable: Keep the area dark, quiet, and free from distractions. A white noise machine or night light can also help.
- Get active during the day: Encourage physical activity during the day, especially with exposure to natural light, to contribute to a healthy circadian rhythm and make it easier for your toddler to sleep at night.
- Engage in soothing activities: Include soothing activities in your bedtime routine, such as reading a book or giving a bath, to help your toddler relax and feel reassured.

Night terrors
While night terrors can be scary for parents, they are harmless and much scarier for you than they are for your 18-month-old. They are not dreams or nightmares, but a fear reaction that occurs when the central nervous system is over-aroused during the transition between deep sleep stages.
If your 18-month-old is experiencing night terrors, there are a few things you can do to help:
- Address any stress in your child's life.
- Avoid screen time before bed.
- Avoid overtiredness by ensuring they get enough sleep.
- Maintain an age-appropriate bedtime.
- Ensure your child feels safe in their sleep environment.
- During a night terror episode, try patiently waiting it out without waking your child. Stay close by, speak calmly, and ensure their safety.

Teething
To soothe a teething toddler, it can help to provide them with something to chew on, such as a teething ring or a hard vegetable. Applying pressure to the gums by massaging them with a clean finger or damp washcloth can also provide relief. It is important to avoid using gels or tablets that are rubbed on the gums, as these can contain harmful substances.
If your 18-month-old is teething, it is important to be patient and provide comfort and support. This stage can be challenging, but it will eventually pass as your toddler's teeth emerge.

Hunger
Babies under 6 or 9 months usually have physical needs, like hunger, whereas older babies are more prone to developmental disruptions, like separation anxiety. However, separation anxiety can also cause sleep problems in toddlers. It can make them resistant to going to bed, cry out once they are in bed, or fail to get back to sleep if they wake up in the night.
Toddlers need 11 to 14 hours of sleep per day, divided between their nap and nighttime sleep. Most drop down to a single daily nap by 18 months of age. If your toddler gets less sleep than they need, they may become overtired, resulting in a bout of sudden, uncontrollable crying.
If your 18-month-old is crying in their sleep, you can do a quick check to rule out hunger. Think back to the last time they ate and see if they might be hungry. If there are no clear indicators of hunger, it could be something else causing them to cry.
