i have just stopped b/f my ds who is 4 mths. he is now in a routine in the day which is good. i have just stopped co-sleeping and he falls asleep well in his cot. i give him a dream feed at 11 but he still wakes every 1-2 hours. i normally just put his dummy in and he falls back asleep, apart from around 1am and 4am i will give him some milk. any suggestions or tips to help ds sleep for longer periods through the night?
