Last few nights with DS2 (4.5mo) have gone something like this:
Feed to sleep 6:30pm ish.
Wake 9:30pm ish - feed 30mins - mostly feeding, some sleepy comfort sucking towards end. Put back in cot.
Midnight - as above, maybe less feeding, more sleepy comfort sucking.
I fall asleep sitting up.
Wake 1/1.5 hr later. Put DS2 back in cot.
Get back into bed.
40 mins later, he wakes.
I feed him. He's asleep within minutes. I wait a couple of mins, unlatch him...he wakes. Latch back on. Comfort suck. I wait a few mins, unlatch, put him on shoulder, he wakes, rooting for boob. I latch on. Comfort sucks. I un latch, successfully put down in cot asleep, get back into bed. 1hr later he wakes. Repeat on and off all night.
I brought him into bed the other night (which I often do) and he was pretty much latched on ALL night.
Apart from the first chunk of sleep after bedtime, feels like he needs to be on my boob feeding/sucking/sleeping all the time or he just wakes.
Teeth?
Growth spurt??
Sleep regression???
Devil child????
