Thanks ladies, he has 10mg in the morning and again in the evening, it's possible that the distance between the feeds caused it so will see how he goes today and tonight and if it continues will take him back to the GP. I believe he is still putting on weight, but is due to be weighed this week so will tie that in with a GP visit also.

I haven't eaten anything that is more acidic or had any changes in my diet apart from less food (ie no upsize lol)

I'm not worried about the vomit just the smell and the fact that with that smell he was unsettled, been a pretty restless morning also :-( poor wee mite :-)
