DD1 will be 4 in 2 months and I need to get planning her birthday party. Last year I did a party at home, but found it really are work mainly due to most of the kids being accompanied by 2 parents. There was a whole load more catering, cost and clearing up etc to do for the adults. DD says she'd like a party at home rather than hiring somewhere out, but I don't know whether I can politely say to parents not to come, and if they'd be happy leaving their kids at this age. Also, do those with experience think I'll be making a rod for my own back as I'll have to look after all the toddlers myself?
