I have a 12 week old baby boy and have done well so far with the bf. Patrick made his own routine, going down at 7pm after a feed and didnt wake till 3 or 4am for a feed then woke around 7am for the day. But last week he started waking at 11pm for a feed then again between 2 and 3am then again between 5 and 6am. As a relult he doesnt feed for long during the night feeds before he falls in a deep sleep and even changing his nappy to wake him isnt working because he just goes straight back to sleep after a couple of sucks. What have I started doing wrong?
