My children, 2,5 and 4 have, get the bucket as Lego Starter Set. The little one is particularly impressed by the animal-building opportunities, the pig and Shaun already see fine out. With the included special stones (eyes, angular stones, 4 wheels are sufficient for a vehicle, ...) you can build really great things. There are also small plates and a couple of long stones (to overbuild around windows and doors) included.
Unfortunately, there is a lack of large 8-stones. While the pack is just enough for a small house, but also because you have already a lot of 4 and 2er block, and that is only stable if someone is helping build ewachsenes. The collection could be phenomenal if again 100 8-would be included, so even small children can build stable walls and houses.
