You have to be completely 100% comfortable with the whole deal about having another baby... including pregnancy, labour and afterwards. I was a month from turning 39 when I had my fourth baby and was happy to have a balance. My first two are now 14 and 12 years and now my second two are 3 and 1 years. I was also over *ideal* weight but that was never an issue as I always felt fine and bp was fine. Only the swelling of the feet was an issue! Happy families any which way.
