LO is 7 months and sleep trained and has been doing great at night, wakes once to feed and then right back to sleep. I'm in the process of dropping his last feed by giving him a bit less in his bottle each night. Haven't fully dropped it yet.

The past few nights, he's suddenly been awake for long periods in the middle of the night. Last night was several hours! For awhile he'll just seem wide awake and happy, kind of talking to himself and looking around and playing. I wait to see if he'll settle but then he starts to get a bit upset, so I go in and feed him, change him, then leave. But then he stays awake for awhile again, like last night. I could tell he was tired, but he couldn't seem to fall asleep. He started to get really upset so I went in to try to soothe him, give the pacifier. He fell asleep briefly, then woke right up again and same thing for another hour or so. Eventually my husband settled him and he slept a bit longer and woke at his regular time this morning, so now he's way overtired.

Did anyone go through something like this around 7ish months? Any idea why he's being so awake at night and can't seem to settle himself, even though he knows how to self-soothe? Is it a developmental thing? Or teething? Or is he hungry since I'm not giving him his full feed anymore, and should I just feed him? I have no idea how to know, or how I should respond to him when he gets upset. He was doing so great and now I'm worried it's all coming undone! Please tell me this is a phase! I'm tired
