My 4 week old DD is EBF and has noy pooed for almost 3 days. She is farting a lot but no poos. We have seen no change to the number of wet nappies. The only thing that has changed in the last few days is she has had one bottle of expressed milk in the evening. She has also had a couple of doses of Infacol as she had been very windy with a gurgling tummy. She hasn't had this for a couple of days. She has also been feeding less than normal but seems happy and not in distress, other than when she is obviously straining trying to poo.
Should i be worried?
