Lots of

all around, especially to Mellyboo! I'm sorry you are feeling so stuck right now. Please don't blame yourself. Some babies just make it harder for us to know how to help them sleep enough. You're clearly concerned about your LO and trying to be the best mama you can. Things will get better. I wish I had some more specific suggestions!
We had a pretty bad night last night

I was disappointed, because yesterday was a PERFECT two-nap day...3/3/3.5 hr wake times, 1 hr 40 mins in the morning and then 45 mins in the afternoon, and NO fighting either of them

but it seems like it just wasn't enough yet. Or something. In any case, he was up every hour to hour and a half between 11 and 4:30, and he was very hard to resettle each time. It seemed maybe gross motor related, because he couldn't lie still at all when I put him down. I don't know

I'm just going to call it a random bad night and try to forget about it! I don't think I did anything wrong.
Bananaz, thank you for your tip about putting him down earlier after nursing

sadly it didn't work for us quite as you suggested, but it did prompt me to experiment with changing the timing, and I think we've found something that works well. He gets really mad if I take him off when his sucking slows down, but if I wait for him to let go on his own and then
immediately transfer to the crib, he's awake but drowsy enough to settle, and he doesn't seem upset about being woken up. So thank you! Crossing my fingers that it continues to work well!
