I know you are feeling frustrated, but it sounds like you are making progress! It may not feel like it, but you are!
One of my girls wakes up in the middle of the night and has a crib party. I've talked about this with the girls in my BC, and around your son's age, many of the babies were doing that. We all said, as long as he isn't crying, just let it be. My daughter will be up 45-60min sometimes. I look at it this way, I've slept through it sometimes and have only heard about it from my husband the next day. So if I didn't know it went on, I wouldn't adjust for it. Does that make sense? I say just ignore him until he cries for you. Then when you go and get him, that's when you start your day. Read his signs and put him down accordingly. Or if it happens in the middle of the night, soothe him. I know for my girls' first A time, they aren't able to stay up very long anyway. Only just started staying up two full hours in the last week. So don't pressure him to go the full 2 hours at first if he can't. Just remember to read his signs for his first A/S time and then the rest of the day will be adjusted.
I know you are concerned that he's only getting 12 hours of sleep per day. When you say he's agitated at night, what do you mean? For how long? Starting when? By what? For example, is he agitated when you are starting to put his pj's on? At 4:30 every night? During his bath? My girls start to get crankety during dinner. The relax during the bath, but get upset when taken from the bath and when I put their pjs on. From there we still have the bottle, and book before bed. They are fine during their bottle, sometimes crankety during the book and grateful to go to bed. It isn't ALWAYS like that, but I know it's pretty regular for us. I chalk it up to the end of the day -- what they call The Children's Hour (or what I call the Meltdown). They've been up, playing, seeing things, practicing skills, eating, watching the dogs, etc. By the end of the day they are over it and just want to crash. They act that way whether they have had good naps or not. One has nothing to do with the other. I don't know if that's any consolation to you.
We start the baths for our girls at 5:30. It seems ridiculously early, but even when they have gone to bed at 7pm, and woken up the next day at 6:30am, they still seem to prefer the earlier bedtime of 6ish. This morning they woke up at 5:40
, and last night we put them to bed a 6:30. Kept them up right now until 8:12, and hopefully they will sleep until 9:45.
When he wakes early from his naps and plays,what do you do? Both of my girls will do this and I just ignore them until they start crying for me. 75% of the time they fall back asleep.
Let us know how you get on!
