Hi there my 10 week old D's is currently on aptamil comfort since he was 2 weeks old due to colic. At first he had a dirty nappy either once a day or once every 2 days. He had a temperature around 2 weeks ago and since then he has had a dirty nappy after most feeds which are quite runny sometimes almost like diahorea and string jelly like mucus. Has anyone had anything similar he's also quite irritable and has good days and bad days which we put down to colic but sleeps well. Just concerned about the mucus and wondering if this is normal ?
