DD is 22 weeks and breastfed apart from one formula feed in the evening which we introduced about 2 weeks ago. Up until about a week ago she was doing one or two poos a day which were mustardy yellow and pretty explosive. Since then she is now pooing after every feed and every poo is green or greeny yellow. From what I've read before both are in the parameters of normal but just wondered if I should be worried or concerned that there has been a change? She is fine in herself and I can't think of anything in her/ my routine which has differed in the past week. I wondered if it is the formula but since there was a week's delay in the poo change I thought it unlikely?
Any thoughts/ advice appreciated
