Go with your instincts, Rachael. If you think something's not quite right then it's definitely worth getting it checked out, just in case. Can you get in to see another GP sooner?

How long has it been going on for? Does Milo seem to be in pain... could it be wind/colic? Do you think it might be the taste of the milk (ie maybe AF is returning)? Will he take EBM from a cup or spoon in the meantime?
