My 2nd son is 15 weeks old. Since he was 5 weeks old I've been attempting a bedtime routine - bath, bottle (he's usually breastfed but I've been trying a bottle at bed time), a kiss and into cot. No 2 nights have been the same but he used to sleep for abou 40 minutes (some nights not), then wake up and eventually settle once we went to bed about 10.30. He would sleep well, waking usually for 1 good feed. i would b'feed him, put him back in cot and he would settle himself in 5-10minutes. The last week has been a nightmare - he will only sleep in our bed. I've tried everything I can think of - bottle, b'feed, putting in bed awake, gently waking before putting in cot, b'feeding to sleep then transferring, a mild version of controlled crying and lifting him after a minute of crying until he's settled and then puttig him back to bed.
I seem to spend hours trying to get him to sleep, neglecting my older boy in the process. He will sleep in the car / buggy and sometimes sleeps on when brought into the house.
Any advice greatfully received! My back can't cope with much more co-sleeping!
