For the past couple of days DD (9 months) has only been taking about half of her normal milk (FF) and is not that interested in her food. She seems really tired all the time - normally she only naps 3-4 times a day for half and hour, but today and yesterday she has been having a nap only an hour after waking up, which is not like her at all. She has not been sick and does not have diarrohea. A lot of the babies we know have/have had some kind of virus at the minute. Could it be she is trying to fight this off? Should I call the GP? I know she is not right, but not really sure what is up.
