tinklebell,
if never poo many days, it's coz baby take just enough of bm or not enough...for my case, my son used to poo once every week....when I intro cereal into the ebm when he's 4mth old, he poo everyday now....poo is still soft, just like when he drink ebm without cereal...
btw, when babies grow older, even if they are total bf, they still need water....for infant, no need water, bm is enough for them...but older babies will perspire or drool, hence loss of water...
when I fed my son water, I realise he's actually thirsty loh....eso when he sweat or drool alot or after his sleep....
