thanks ladies, so just for the record, wipe his mouth out with a wet cloth, milk is a good thing to give (just a small amount) and to watch for vomiting and bubbles coming out of his nose (I kid you not lol), she said obviously if he seems to be having a reaction to take him to hospital. But he hasnt even been sick yet so maybe I caught him just in time.

I was changing DD nappy and normally hear him move the breakfast bench chairs we have locks on the cupboards so guess will have to make sure we put the liquid away now.

Thanks for the tips ladies.
Far out, bubbles out his nose? That would be alarming anyway! Glad he seems ok, surely he wouldn't have had much cos it can't taste great?
