Hmmmm. Not sure about a baby one! I'm actually enjoying not having to constantly care for a little one, its nice to have an older child that you can chat and giggle with!
My DD is growing up fast and I'm enjoying our girly chats! Apparently (according to her) we're really bonding now!!!!
Mind you baby LO's are gorgeous too, but thats where being a Grandma comes into its own! You can do all the cuddling and bathing and rocking and soothing and even nappy changing if you want BUT you don't have to get up in the middle of the night or deal with teething grizzles or temper tantrums or any other noxious behaviour....you can just smile sweetly and hand 'em back to mum or dad!!!!
