Re: Poo problems @ 5.5 months, please help we're so frustrat
I'd blame either teething or a gastrointestinal bug. Teething is often accompanied by a lot of drool, and you can see watery "drool stool" when baby is in an intense bout of teething. A gastro bug can mean something relatively mild- by which I mean your baby might not exhibit any signs of sickness other than some weird poops.
In an otherwise healthy, happy, growing baby who is being fed on demand, green poops are not a health concern. They're just a variation on the normal pattern.
