I am in need of some advice for my 6 year old nephew's upcoming birthday. His older sister just turned 8 in February and we got her horseback riding lessons because we kind of flaked out on Christmas (I had a baby on 12/20), so we need to get him something that is equally "big" and exciting. Any ideas? I would love to do something like we did with his sister and get him something that he could look forward to doing, instead of the same old things that he already has. Thanks!
