any advice? last 2 nights dd has woken at 5am ish and NOT GONE BACK TO SLEEP arrrrrrgggghhhhh. am feeding her ebm at 7pm, (so i can see she is getting a good feed - on the breast she takes little when tired). she sleeps fine til 11 or 12 or 1 or 2 if i am lucky! has another feed then wakes up at 5 never to return to slumber land. what am i doing wrong? she does have a big feed. do i need to give her another bottle to make sure she's taking enough? because don't think i can express 2 bottles per day and i dont really want to give formula again, just out of preference. Previously, she has always gone back to sleep after all her feeds until 7 or 8 am. I am shattered!
