My kids being 5 and 4 have never carved a pumpkin. Actually, they still haven't. I did carve a pumpkin for them this year though. The girls wanted nothing to do with sticking their hands inside and getting the seeds out but the boys were willing to help me.
I told them it had to be a happy pumpkin, so that is what it is.
I tried roasting the seeds when I was done. No one really liked them, so they are now sitting in a baggie and will probably going in the garbage some time soon.
