Our DS will be 4 in Sept. Recently he has switched from liking Thomas and Bob the builder to really being into Spider man but mainly all these awful characters such as the Lizard?! Carnage and wolverine (hope these mean something to someone as I had never heard of them before!). All his play revolves around these characters fighting and hurting each other, and we are starting to wonder if this isn't a bit young to be into all this kind of stuff. We presume he has picked up these characters from nursery and yes we have foolishly bought them for him to reward him for extra good behaviour. I know that my parents are mortified when they hear him playing, and it's now got me concerned. Also he's mad about watching Scooby Doo, but again DS always wants to pretend to be the monster and goes around attacking his little brother. I'm sure these toys are affecting him in other ways as he's becoming a really bolshy little boy, verbally and physically aggressive at times and hard to control. Or are most boys like this at this age? We don't really want to remove these toys as he loves playing with them so much, but equally don't want to be encouraging inappropriate behaviour. Anyone who has any experience on this please post a message, I'd be really grateful. Thanks.
