Amandamillie - you are so NOT ALONE!! I have a almost 10 week old, who like yours, is also bottle fed and sleeps okay during the night, but struggles to sleep during the day. I'm not really convinced its helping but I am giving him colic powder before each day feed. You can read my post "day time sleep troubles - 01 March" in this section and see if that sounds familiar. In my case, I have discounted the idea of reflux as anytime he is on his back he is happy as, its only when he has to go to bed that he plays up. Sorry I can't help because I haven't found the solution for my wee man at the moment, but just wanted to let you know that there are others out there with a similar/same problem. Keep smiling - for whatelse can we do?!?
