taking DS, who has just turned 5 to natural history museum and then to see the xmas lights etc. We're having a dilemma whether to take a pushchair. We don't own a pushchair anymore and he walks brilliantly, but i know hes going to get really tired and if we have to end up carrying him it'll break our backs and ruin our day. Would you frown upon a 5 year old in a pushchair, or shall we borrow one and all have an enjoyable day? (Ooo, i can hang Selfridges bags on handles too when i max the credit cards!)
