Sleep fact for 20 month old babies
Some toddlers this age will suddenly start to protest at bedtime due to rearing its head again. Consider experimenting with leaving their bedroom door open or introducing a night light (choose one free of blue light). These measures can help your toddler feel more secure at bedtime, while still maintaining healthy independent sleep habits (a.k.a. you don’t have to spend an hour trying to silently creep out of their room after helping them fall asleep). We recommend closing their door after they drift off to sleep. In case of a fire in your home, having the bedroom closed may help slow the spread of fire and smoke.

20 month old baby sleep FAQ
Q: Why is my 20 month old suddenly waking so early?
A:
A sudden change in waking time is often a sign that your toddler’s schedule needs to be adjusted. Not all children can easily go 12 or more hours between meals, so one thing to investigate is if dinner is too early. For example, if dinner is at 5:00 PM, you might find your child waking at 5:00 AM. If dinner has to be that early, try offering a protein-rich snack closer to bedtime (but before teeth brushing). You can also consider whether the last wake window is age appropriate (usually around 5.75 hours at this age). If the awake time is too short or too long, that can contribute to early rising.
