Caramel & Starshaped: Given that my experience is only with F, you may want to disregard the following, in favour of some more of Ali's wisdom.
I've always just fed F back to sleep. If he's not hungry, he'll just snuggle into my boob and go back to sleep. I had a short phase of wondering if it was the right thing to do, but kellymom reassured me that it would be stupid not to use that tool!
When he went through a bad sleep stage, I fed him, and if that didn't settle him I'd just put him in his cot and go back to sleep myself (NB he was just happy and awake, talking to himself, not upset or anything). I'd wake up a while later to find he'd fallen asleep himself (the beginning of his occasional self-settling skills).
However, he does feed every 2 hours during the day, and has done for a couple of months at least. He only naps for about 35 mins at a time, and has about 4 naps a day. I think he needs more sleep. I think he needs to sleep for longer. But he very rarely does.
Normally (i.e. on a good day!) he's in bed by 7, and asleep by 9 latest (after a 35 min nap & feeding back to sleep). On a good night he'll wake for a feed anywhere between 2-4am. I think the good night's are becoming more common!
However, when I go back to work, and he's faced with bottles all day, I fully expect him to reverse-cycle. Especially in the beginning. I'm not entirely sure how I'm going to cope, but I suppose like everything I'll have to ride it out.
F's so close to sitting by himself today. He's been sitting surrounded by cushions. Although now he's reclining watching Planet Earth in HD!
DH has gone back to reading the BLW book. He's now finished chapter 3! I must restrain myself. Must wait till 6 months!
