My SIL has requested we get a "big box of Lego" for our nephew (6.5) this year. Am happy to oblige but no idea what to start with... My daughter (7) has a pink box, but can't find equivalent blue one, there's either a farm one (too young?) or a huge one for £40. My limit is £30 really. Any help? Don't think he has much already, so think we're kick starting a collection rather than adding to one like the city/ninja/Star Wars... SIL didn't seem keen on those..
