hello Cathy
Congratulations on your surprise news, Im not an older mum but 3 of my neighbours had babies last summer the oldest was 47 and the youngest 43, all three babies fine and healthy. The one thing they did say was they felt this pregnancy more then the others, one said she had suffered with every pain, lump and bump, she put it down to old age. You should see this woman she looks like a 37 year old not a 47 year old, baby keeping her young.
Good luck and hope all goes well
