I have always put my 4 month old (tommorrow) ds into his cot awake at bedtime (7pm) and soothed him if crying and left him if ok and he goes to sleep by himself. However, when he wakes in the night (at best 12pm, 3am, 5am and 7am; very occasionally 12, 4 and 6.30ish) he falls asleep while feeding and I daren't wake him as if he cries he could wake dd (2 1/2). but I know he can't get himself back to sleep without milk as if he wakes unexpectedly after just 2 hours he won't settle without milk and cuddling him back to sleep without no longer works. I'm intending to put him in the cot awake at least the first time he wakes to increase his ability to sttle himself, and risk my dd waking, any advice?
