when is sick, too much sick?

[isil]

Alasdair has always seemed to be a sicky (vomit) baby. That's fine, I've just dealt with it. But I'm starting to wonder (almost 8 months on lol) if he is too sicky. It's always milk based sick but often mixed with his solids. If I give him yoghut then it's just like he's had milk. He was like it on breast milk just as much as he is like it on formula.

I guess I'm just a bit worried because the HV was surprised at how sick he was quite a while after his formula at his check yesterday. And to me, it was nothing!

Am I just worrying over nothing?
