my baby girl is fed on breast milk and formula milk both and she hasn't pooped for 2 days and 5 hours what should I do is it normal she is 21 days old and 36 week late premie

A. Please do not worry about it as kids can go without pooping for two weeks also at a stretch the condition is that the urine output should be good the feeding should be proper and there should be no discomfort and it is natural if you feel any of the problem is there apart from constipation any discomfort then you can insert a suppository
