Ds2 is 13w 4d. Over the past few weeks his nighttime sleep got longer and longer, and he now tends to sleep from 9.30pm til around 7am, sometimes later, which is fantastic. However the problem is getting him to sleep in the first place. Until 2 weeks ago I bfed him to sleep then lifted him into his cot. 3 weeks ago he started getting a formula feed at bedtime, and we decided to try to break his comfort-feeding-to-sleep habit. Sometimes he'll watch his mobile happily then drop off to sleep 10 minutes later. But mostly he is devastated the second he gets put down in his cot. DH does the whole bedtime routine to give me a break, and also because ds might be more upset if I'm with him but I don't comfort him to sleep.
What do we do to encourage him to happily lie / fall asleep in his cot?
Currently, dh takes him upstairs at around 8.30pm with 8oz of formula. He quietly feeds him in a dim room with the nature sounds playing on the mobile. Ds gets drowsy and full up (he doesn't always have thr full 8oz), then cries and cries when he's laid down in the cot. So dh picks him up and comforts and rocks him. Tries to put him down again, same thing happens. Ultimately ds falls asleep in the middle of sobbing, in dh's arms. How do we fix this...? Why does he get so upset about being laid down at bedtime?!
During the day he will only go to sleep either bfeeding or in his wee swing, but can get annoyed when he's put into the swing.
