We live in cambs and would involve a train journey. They have never been to London. I have only occasionally been my husband lived there till he was 12. My dh really wants to take them during the holidays. I dont for a number of reasons I feel they are too young and I not sure I have the confidence it seems such a daunting place to take small children. What do others think? My dh is thinking somewhere like the natural history museum and a picnic in one of the parks.
