So my 8 week old is on prescription milk due to cmpa she was on hypoallergenic aptamil pepti 1 but they ran out and now they've given her SMA lactose free formula.. she has 1 poo a week of lucky but today she had a poo explosion this morning greeny/brown and just had another poo the same colour but a lot runnier and A LOT of the 'seedy' looking things.. is this normal? Any advice welcome x
