We have a gorgeous DS called George and although we haven't started TTC we've been thinking about baby names for the future.
If we had a girl next time it'd be Rosie for sure.
Does George and Peter sound good?
I love the name Peter but I hate Pete!! And I think "baby peter" would remind me of that poor boy that was killed by his mum and her boyfriend through neglect. 
But I suppose you can't not name your child Peter because of that, he would soon outgrow the "baby" part
So George and Rosie, then maybe George and Peter?
