Hi - anyone else experienced this? My 11 week old baby seems to have frothy stools pretty regularly since she was a few weeks old. Sorry for the detail, but it looks like cappuccino froth at the start of a movement, but is interspersed with normal baby poo. Is this diarrhoea and if so, why does she keep getting it? She's a colicky baby - could this be the reason? My doc though the inital bout was a dodgy tummy and advised me to keep bf.
