Is it normal grandkids to be so unappreciative

Smack them 'round the face and don't give them dinner.

Welcome to the new generation! I'd start giving the kids a little less, you know, of toys and stuff (not food, unless their overweight :)) That's so sad that they don't appreciate what you do for them. I pray that someday they will appreciate you. :)

dont allow it kids always think they deserve everything

It seems kids these days expect a lot more, and they want to do a lot less. Back in my day, I always had to do chores every day. That's how I EARNED my weekly allowance. I respected my elders - especially my parents and grandparents, and I still do. I don't talk back to them, and I'm always polite. I also offer to help them whenever I can... and I don't expect anything in return (like money). And guess what? I'm only 27. The world has changed SO much since then. Kids also wanna grow up way too fast these days. 12-year-olds think they're 20! I always wanted to stay a kid forever. This world scares the crap out of me so much, I'm affraid I don't even want to have kids, in fear of how the world will be in years to come.

Maybe your just to needy

Ummm they are kids lol. Please don't look at things from a mature adult perspective. With children, adults are only as good as how much they enjoyed their last interaction with them. While kids may have some ability to reason matters like adults, they often lack the ability to see the bigger picture.
Sure you can talk to them about responsibility, chores etc.... But with them, Its hard to appreciate what they always have had-which in this situation is loving Grandparents that care enough to take care of them. Hang in there and God will bless your for your hard work.

My bad 4! 9 and 12. I rest my case.

They're 9,10 and 12. Give them a break they're kids. Of course they're not going to appreciate what they have. Give it 6-8 years.

I wish my grandparents were stii around, they passed when I was 13. They should be cherishing the time they have with you and do everything they can to make life easy on you.

I hate this. I have a similar situation on my husband's side. His grandkids, his kids even, just don't care at all. His ex-wife, however, married a rich guy and they get treated very well. It's sad, especially as your husband us a retired Vet. Sad those kids have no respect. Some of my husband's grandkids are in college (fully paid for, naturally) and have NEVER even had a job. Imagine that? Yet they complain about everything. Your husband is a Vet, how could these kids today ever see eye to eye with that? I think it's a real luxury to complain. Only spoiled people have time to complain. Those of us who have lived and seen hard times just are happy to live in peace. God bless you.
