My DH and DS's birthdays are 12 days apart. My DH said that if we were going to have a second child, it had to be before his 40th birthday. DS was born 12 days before DH turned 40. Whew...just made it. Good thing DS wasn't late...I might have had to give him back
They are turning 10 and 50 this year (we will be celebrating both on our upcoming cruise)
