What age do children grow out of Ben 10 toys and DVDs?

[trainsandplanes]

Just that really, DS has been into Ben 10 for a few months, mainly because his friends were, but now he is totally obsessed with it! He's 4.6 and I was just wondering how much Ben 10 stuff I should or shouldn't buy in case he grows out of it. How long will he play with it for?

(bitter about Thomas being outgrown!!)

ds just turned 8 and they have outgrown
ds says 6 yr olds still like ben10

so maybe these toys will have 2 or 3 years...not too bad!

ds1 LOVED it in reception and yr1

now in y3 aged 7yrs he says he hates it, but i think that is more to do with the fact that his 3 year old brother has discovered it.!
