I am in London for a day with my ds (2.5 years) and wondered if he would be up to a museum. I was thinking either Natural History or Science - are either better for this age or too much. Any other suggestions on what to do for the day would be greatly received. We are going up beginning of December and I am sure a trip to Hamleys will be on the agenda also (and for me to see the lights as well as him!).
