Our little boy is one in December and we are thinking of having a little birthday party at home for him - inviting the mums/dads and babies we've met from antenatal/classes etc, family and friends. Quite a few of the babies have older siblings between 2-4 so I'm after some idea for activities for them? DS is our first child so not really sure what would appeal to older slightly children? I did think about colouring books/play doh for the ones nearer 4, but then thought there's potential for messy/ruined clothes etc and not sure the parents would thank me? Any one have any ideas? Also - would you do party bags for the babies? If so, what would you put in them?
