My dd up until tonight has been feeding every 3/4hrs, and sleeping well. Tonight she took a large feed of 4oz at 5, woke again at 7.30 slept til 8.30, took another 3 oz but hasn't settled since. She has had bad wind and some huge burps, but nothing else seems to be shifting. She seems tired, will take a small feed of an oz when offered but then resumes crying. I have changed her nappy and am running out of ideas. Any ideas mum's?
