Harry has been quite sick yesterday and today after each feed

- he has been ok since he went onto formula but seems to get more sicky when we start a new packet of formula (same brand, just a new box)
Dh seems to think that this could be affecting his tummy with the formula being a different batch to the last one even though it's the same brand of formula????
Has anyone else experienced this?
I mentioned it at the clinic today when I took him to be weighed and they said they'd never thought of this before, he's putting on weight like a trooper so not too worried but it is sooooo frustrating when he is sick.
