First, common reasons for sleep regression for kids 18-24 months:
- Night terrors
- Separation Anxiety
- Molars coming in
- Disrupted sleeping pattern (vacation/out of house)
- Developmental milestones
I think it may be a combination of all of them except night terrors. Over December holiday, we stayed at the in-laws for a few days. Wouldn't nap in his pack and play at all. I made the mistake of cuddling in bed for his 90-120 minute nap for one nap, and laying next to his pack and play in the bed for the other. After we got home, things seemed fine for a few days.
On New Year's Eve, is when things got really bad. He woke up screaming bloody hell in the middle of the night. We let him cry it out for a few minutes, but then it got noticeably worse. Our little angel decided that was a great time to climb out of his crib for the first time.
Since then, he has been getting up every night somewhere between 1am and 5am. He will not go to sleep without attention from us. Different things we've tried over the course of the last two weeks:
- Waiting outside his door until he sleeps, then ninja escape.
- Waiting in the chair in his room until he sleeps, then ninja escape
- Sleeping on the floor in his room until he sleeps, then ninja escape
- Letting him cry it out, which lasts for over an hour until we give in to 1, 2, or 3. What isn't fun about this, is that this totally disrupts his older brother's sleep which isn't very fair to him.
Before all of these shenanigans, he usually slept straight through from 8:30pm to 7:00am, with a 2 hour nap during the day. Here is our before bed routine for reference (which has worked for the many months prior):
- Brush Teeth
- Say goodnight to brother
- Leave right away.
I'm guessing our inconsistency has been hurting the situation, but two weeks in we are at a loss.... help!
