I'm not sure where to put this so I will start with the Teen section. DS just turned 12 and Lego's are his life. They are basically the only 'toy' he uses. I know each kid is different and each kid had different likes and interests.
If you have a lego maniac.how long did the passion last. I have an insane amount of $$ invested in Lego's and DS does love them, he takes excellent care of them, and basically assembles them and puts them on display.
I don't want to say 'no' to buying the larger sets (very expensive) but if the lifespan of this obsession is short lived and something else is going to take its place - please let this ma'am know.
We have a couple Lego stores in our area and yes I realize sometimes the passion just never ends,
FWIW- DS loves math, physics, chemistry and is basically doing all STEM classes. I have no problem with LEGO'S.
