i would assume baby is on TBF means no cereal nothing?
does baby seems to be in distress or stomachache?
if not, it's perfectly fine..
as baby grows up, their digestive system absorbs better.. and breast milk being the most easily absorbed food, gets almost all digested up by baby's digestive system.. thus no pooping coz there is nothing leftover to poo..
my dear daughter was once 10days w/o poop.. the longest 'record' i had heard of is 14days.. but wen she finally poop, the smell is OMG.. i almost vomited.. nothing like the usual poop smell, n not even like the adult smell.. but still in soft state.. not tough like how constipated poops are..
but having said that, this only applies to fully TBF babies..
