Lahnee didnt like to sleep in her cot during the day until she was 5mths and she would only sleep on her tummy. We ended up setting her portacot up in the lounge as I think she just wanted to be near me and the day to day sounds were comforting. Also, when she was 6, 8 and 12 weeks she had serious growth spurts and wouldnt sleep in her cot or portacot, and would only sleep on me. These were really hard weeks as my little 'parrot' was constantly on my shoulder or on my chest (when I would sleep too). I was scared I was setting myself up for a really nasty sleeping habit, but when the growth spurt passed so did her need to be so close to me. Not sure if its much help, but sometimes the 'general' advise on how to get babies to sleep doesnt always work. Just be willing to try something different...
