Ds1 is 5.5 and is 2nd of 4. I think he has been more affected by the birth of DD2 than I thought - we probably focussed a bit too much on how DS2 (2.5) was feeling and assumed DS1 would be fine. Anyway, half term is coming up, and DH and I thought we would leave the two little ones for the day and take the two big ones on an adventure, to have a bit of undistracted attention and fun. We live in N Wilts near the M4 and are happy to go almost anywhere - beach in N Wales? Legoland? Cadburyworld? We'd like something that involves a bit of running around, but also something interesting and "grown up", ie that a 5 yo would enjoy but a 2 yo wouldn't. Visit a castle? Alnwick? (Although that might be more than a day trip from us). Go-carting? I'd really appreciate any suggestions you have - the more off the wall the better. Thanks!
