We are visiting London in August and need your opinion please! We are bringing our son who is 4 and 1/2 and want to visit the science/ natural history museums, Princess Diana park and go and see a show. Maybe a little sightseeing. The big question is: Should we bring a pushchair ?? I was thinking yes for ease and to stop the inevitable whine of 'I'm tired; carry me''. Husband thinks it will be way to much hassle and we'll jump on buses or underground when he gets tired. Are these things close enough- we would try to get accommodation close by. He never uses a pushchair at home I'm just worried we want to get around and the walking will be too much for him. i know when I last visited pre- child I was knackered!
