Christmas is expensive, and presents that are opened and then sit in the cupboard all year are a disappointment to everyone. Especially when you are buying the first sets, you want to make sure your LEGO investment will be a set that your child will like, and will open up a huge world of creativity for them.
The most important thing is to start by thinking of LEGO as a creative
puzzle toy, rather than a brand. Following a LEGO instruction book to
build a model is not so different from following any model
instructions, or even completing a jigsaw. The difference is that once
you've finished, you can play with it, dismantle it and rebuild it
however you want.
Choosing might be more simple than you think, and to me has 3 main questions:
1. What toys does your child like playing with?
2. What is your price range?
3. What age and ability range is your child?
