4 month old has cottage cheese like white lumps in her poo and her poo is more green than yellow. Also more gas which is smells bad. Has taken 180 mls less formula than this time yesterday... Ha only taken 520 mls today and one feed to go. Took 900 yesterday. Alert in self and no concerns re urine output.
This seems to be a case of lactose intolerance. Lactose is the carboy Chat Doctor.  When the child is unable to digest it, the undigested remains are degraded by intestinal bacteria to produce foul smelling gases while some amount may pass unaltered as cheesy lumps in stool. I would suggest getting a stool routine microscopy (including test for reducing substances) to be done. Treatment will depend on the results. In case of presence of reducing substances, I would suggest changing the formula to a soy based formula and see if there is a difference.
