I don't think she has milk allergy, but I'm not sure. she just turned 8 months old and I give her porridge in the morning, usually boiled with water and then mix it with little bit of her formula (cow&Gate, 3rd stage with iron). I thought I try making porridge with real cow's whole milk, then she started to get horrible smelly poos, almost diarrhoea like, tiny bits of green poo. And this accompanied with terrible nappy rash. I didn't know what it was so I took away milk, dried cranberries (all dried fruits), and any acidic food I could think of and it seems to be getting better now. I know Cow&Gate is made from cow's milk, so I'm not sure why milk would cause this? Or could it just be teething or bad tummy?
