Hello,
My 18 month old LO is having major separation anxiety. This started after we came back from a one-week trip in Hawaii early April and just when he turned 18 months. In Hawaii, he slept in a pack-and-play in the same room as us, and only on two nights, we put him in bed with us when he woke up at 5am (and he slept until 7am). Also, on the plane, he slept on us. Other than those instances and some sleep deprivation from a few short naps and later bedtimes due to travelling, nothing really changed in Hawaii. Once we got back, he has had major separation anxiety - he cries hysterically when I leave him at daycare (which did not happen before), he refuses to fall asleep on his own (he needs to be held/rocked/walked to sleep and it takes an hour to do that) and he wakes up 2-3 times a night crying hysterically. He used to be a very good night sleeper and he would fall asleep on his own and wake up talking to himself.
We have tried making him CIO 3 minutes at a time, but after 10-15 minutes, it is too painful for us because his cries seem more desparate and hysterical than those "I want to fall asleep, but I can't cries". We also tried sleeping on the floor next to him and climbing into the crib with him, but none of that worked. He has been transitioning from 2-1 nap and we have been seeing whether he is undertired or overtired, but on both instances and when we think he has caught up on his sleep, he still has trouble falling asleep and wakes up during the night. Hence, my preliminary conclusion is that this is 18 month separation anxiety.
What can we do to help him, or do we just wait it out? I am afraid that each night when I end up holding him to sleep, it will form a bad habit. I have been trying to PU/PD and modified CIO (like I mentioned above) and just any other way to comfort/support him without spoiling him too much, but after an hour, I end up holding him to sleep because I am exhausted and I just want him to sleep so his next day will not be horrendous.
His schedule looks like this:
7am - Wake up
11:30am - 1st nap
3:30pm - 2nd catnap
8pm - Bedtime
*When he is at daycare 2 days a week, his 1st nap is at 1pm and then sometimes he falls asleep in the car at 5:30pm on the way home. He naps for 1.5 to 2 hours total a day.
Any thoughts on this would be helpful. Thanks!
