Planning DD1's 5th birthday party for the start of March. I have a love/hate relationship with party bags and thought it would be a nice idea to send everyone home with a piece of cake and doing a lucky dip on the way out with wrapped up party bag style toys so everyone gets one surprise thing instead of a bag of tat. Plus it'll be her class plus cousins and family friends so about 40 children....AIBU or is this a good idea?
