Having three kids myself I have to say, selfish as it may be, that I hope to have grandchildren some day
One day I hope to have grandkids too, biscuit. If my son decides not to, it won't be the end of the world, but in 25 years or so (my son is 6), I kind of like the idea of having them around.
My mom was always very nonchalant about grandchildren - she said she'd like to have them, but has never been wild about small children and she never pressured us. My brother had his first child about three years before my son was born, and there was even less pressure after that. My in-laws were absolutely hammering us for grandchildren the minute we got married. They're the type of people that firmly believe NO ONE can be happy without children. It came up in, like, every conversation. We told them to stop holding their breaths several times, and eventually they got the message. They were quite happy when we had our son, their first grandchild. Now my mother in law watches her daughter's two kids daily (ages 2 and 6 mos.) and even forbade (yeah, I know) her daughter from having another child until the youngest is three...but, now she's started up on us having another baby. I seriously don't know what her issue is.
I'm with you, bakergirl - I'm not sure if I'd have had children without it happening as it did. I don't think I'd be heartbroken if we don't have another.
