Well, I had the same problem with my kids when they were younger. You can try to put a sock over their hands when they are at home. I tried every kind of sauce there was......it didn't work.....although I do believe they have some now especially for that. You need to ask them why. Especially the older ones.
I'm sorry to hear you were laid off. I was too in Dec. I found a great work at home job and I'm loving being home. if you're interested in more information, let me know. Good luck with the grandkids. I have 8.....
