I hate children in adults stuff, & for me that is clothes, makeup, nailvarnish & I even dislike ears pierced (I am going to make mine wait a long time but I hate it when you see babies & toddlers with them done - I am sure a lot of people will disagree with me on this one)
Another pet hate is young children drinking fizzy drinks - our eldest (3 1/2) knows these are grown up drinks which she is not allowed, the most she gets is a sip if we are at a party! We went to a childrens birthday party & one Dad poured fizzy (got for parents) for his Daughter which confused all the others no end although I was pleased all the other parents were saying the same as me!
