My DD is almost 13 weeks old and has been on Losec (5mg two times a day) since she was 5 weeks. We saw quite a big improvement but the symptoms have started returning. She has also had very frequent dirty nappies filled with mucous. They are also greener in colour when they are normally yellow. She usually only has one dirty nappy every two days and she has been doing at least ten a day for the past 3 days. She has dropped 110grams since Sunday which is a fair bit considering she is only 4kg. Is it possible that her reflux has caused the diarrhea and mucous and that it will be as simple as increasing the Losec?
