I feel like I should know this as DS is DC2, but I don't think I ever got it right with DD either, so here goes.
I had high hopes for DS's sleep as he is so much better at self-settling than DD ever was - for naps and bedtime I can put him down awake and he will more or less settle himself to sleep. As a newborn and up until about 2.5mo, he was doing 6 hour stretches during the night - so I thought I was onto a winner!
Anyway, he's now 3.5mo and for the past month he's been waking every 1.5-2 hours throughout the night [sigh]. I partially cosleep and slide him in next to me when he wakes, feed him lying down, usually fall back to sleep myself and then slide him back over when I wake up again. Doing it this way means I still feel like I'm getting enough sleep, although I wonder if it's part of the problem, but that's another thread. I wonder whether I should be trying to settle him without feeding, but I a) just choose the easiest route back to sleep for him, me and DH and b) don't feel confident enough that he isn't really hungry.
When he wakes and I put a hand on him to see if he'll settle, he grabs my hand straight away, takes it to his mouth and starts sucking vigorously! He seems really hungry, but can he really be hungry every 1.5 hours all night?! I want to have a go at helping him to settle without feed for a few wakings, but I know I won't be able to hack it if he starts crying and I constantly feel doubtful that perhaps he really is hungry.
During the day he feeds every 3-4 hours, short feeds, but they've always been short and so was DD - think I have a fast milk flow and he gets quite a lot in a short space of time.
Sorry - this has ended up long, but any advice from anyone with more knowledge than me would be much appreciated!
