One of the mums at nursery has asked if my dd and hers would like a joint party next year. I'll be eight months pregnant and she's offering to organise it all which is great, but she seems to be working to a budget of about £300 between us. That seems a little ridiculous to me, I mean dd is only four. Am I being ungrateful? Is this a resonable amount? £150 for a four year olds party seems an awful lot. What do you guys do?
