Am I being a selfish grandmother?
Our son and his girlfriend ask me to babysit our grandaughter (5 months old) occasionally. Most times, it's for about 4 hrs. and I'd rather not babysit longer than an hour or two. 4 hours just seems like too much for me. They usually get me to watch her about 1-2 times p/mo. Am I being selfish for not wanting to be tied down to this for such a long period? I know if I said anything, his girlfriend will really take offence to it. I've said no before, and she gets very upset, and won't ask me to watch the baby for a long time. She makes comments like "Oh I'm so glad we can give you a chance to be with your grandaughter by you watching her". It's not that I don't want to spend time with the baby, just not for such a long stint.
Any suggestions, or is it me??
