Thanks everyone for your replies. She has a Paed checkup on Wed anyway so am going to discuss it then. The GP last week said that noises were normal but I don't think she realized how loud they are! What is interesting is that she doesn't do it during the day and not when she is first put to bed but only from about 1 onwards or so. It's almost like when she has already been lying down for a while, it starts? My Dad (who looked after her for an hour last night) noticed that she seems to be struggling to get out of her sleeping bag do we are going to try one size bigger too.
