We do early evening on the 31st with our 3 yr old and 8 yr old and 3 friends each. We buy some fun Halloween craft things to do first then only go up and down our own street, only knocking at houses with pumpkins... I also post a note the day before asking 3 nice neighbours whether we can call at 6pm and offering to give them sweets to hand out, so we are assured of at least 3 or 4 positive welcomes :-). Personally on that basis it's a fun half an hour for all and then the condition is that only around 5 sweets are eaten on the night - the rest are saved for another day. Everyone on our road seems to enjoy going up and down and if we've taken away the pumpkin at bedtime people don't call any more... Happy Halloween to all, and may everyone's nights run as they personally wish...
