My DS's poo didn't change till he started solids, and now it can still be a bit sloppy at times (not like the BF poos though). He stared pooing much less often around the four month mark (I think?), like every few days or so, so the changing pooey nappies wasn't so constant, it was just every now and again.

Eeww... what a yucko post. I HTH.
