When lachlan was in the hospital he was sleeping very well and the only trouble I had was breast feeding. I did not have enough milk so we decided to bottle feed using nan which seemed to work well the first ten weeks and he was waking up every four hours for a feed and going to sleep straight away at night. When he was 10 weeks old he became very unsettled and would wake up at 2am thinking it was party time and he would not go to sleep untill 5 or 6am! It was very frustating for my partner and I and we tried everything controlled crying, wrapping him, rocking him and nothing could settle him so we went to our local doctor for a solution and he suggested changing his formula to S26 and it is working! He is now 3 months and is sleeping from 10pm- 6or 7pm we now have a happy baby!
