Ryan did the same he would poo 4 - 5 times a day in the begining then at around 12 weeks just didn't go for 7 days and wow on that 7th day the flood gates opened i was like OMG this can't be good and he was then a 7 days poo machine then when he was 5.5 months old went back to once day the MCHN assured me it was fine for a BF baby to go up to 10 days without pooing as they use every bit of milk they ingest where as FF bubs apparently don't and they need to poo more often
