My 9wk old son recently has been acting as if he is fighting sleep, he is drinking a full bottle (6oz) as he is a very big boy but he just doesn't seem to be settling down to sleep after! Today for example he must have sleep for a total of 1.30/2hrs in 20min/30min spells from early morning and we were out walking and at the park in his pram all afternoon as well. Now he is fighting sleep in his crib, closing eyes as if he is falling over then walking up with wide eyes and trying suck his hands! He won't take a dummy either. Help! x
