DS 3rd birthday is coming up and although I want to give him a party I really do not want anymore toys etc. Our house is getting overrun with toys/puzzles/games and both DS play with around 10% of what they have already. Would it be considered rude if I asked people on the invitation not to by presents but to make a donation to a children's charity if they would like to? I have no problem buying presents for my friend's children but with two children now I feel that the amount of stuff they have accumulated in the last three years is getting a bit crazy. I am from New Zealand so I am a bit paranoid about making a social blunder and offending my lovely British friends:-).
