My baby is just over 4 months , she sleeps through most evenings, last night she slept from 830pm to until 730am. Her night time routine is feed, change, lights down, feed and then she often falls asleep. 90% of the time she falls asleep on the final feed, the other times she falls asleep with a white noise app. Clearly she is sleeping like a dream and I don't want to upset that but I keep reading that she should fall asleep straight after a feed and should be able to fall asleep by herself . How much should I worry about this? Has anyone had any experience of waking a baby postfeed does this work? I am very reluctant to try it. Thanks in advance x
