Hi just looking some advice. Since my 4 yr son got numberblocks for Christmas he has been become increasingly obsessed with them. He enjoyed numbers before this and is really good at simple maths - he can count and can add simple numbers together etc. However, he has started making numbers out of the blocks - ie 17 and talks to them like they are real and even wants to take them to bed!! Probably because on the cbeebie show the numbers all have their own personality I think. He has stopped playing with a lot of his other toys and only wants to make numbers (and they can be out of anything if he doesn't have blocks). Should I try to broaden his interests by limiting the numbers or should I just let him play away if he is happy. I just see his interests getting increasingly narrower. I'm not sure what the right thing to do is? Sometimes it drives me crazy - as at times the first thing he says when he wakes up is "two tens are 20!" or "5 and 2 is 7" Maybe it is just a phase that will fade away. Everyone else thinks it's great and all I hear is "he is going to be an accountant"...but I just worry about whether I should encourage or slowly try to limit. Has anyone else had a similar child? Many thanks,
