Hi my baby is 7 weeks today and hasn't been for a poo for 2 days. Before this she was having about 15 dirty nappies a day as I was breastfeeding, howver, since I have started giving her formula (as well as feeding her a two or three times a day myself she has become constipated at least I think she is, I am not sure as she hasn't actually done a poo so I don't know if it is hard or not)! I have tried a little sugar in boiled water and fresh orange in boiled water and I have cycled her legs and massaged her tummy as well as given her warm baths... as yet nothing has worked. She is still sleeping ok and seems to be feeding ok but is straining a lot as if she is trying to do something but can't also she is quite windy and it is smeller than usual! I may be worrying unduly but I don't really know what else to try.... any advice would be really gratefully received.... at what point should I think about taking her to the doctors??? Thank you in advance....
