Dreamer, I am 46 and my husband is 47. We started having kids young (by today's standards). Our oldest is 24, with a 2 year old. We have 8 kids and our youngest is 3 1/2! I was nursing her at my daughter's wedding. She and my grandson are 18 months apart. He was lving with us from Dec. till Aug. and it is more of a challenge to have little ones around as you get older. I've had babies and toddlers around for 24+ years now. I think the hardest part will be childproofing and making sure the house is safe for little ones. If you are in good health and have a lot of energy (especially mental energy!) you should do fine.
