Are you prepared to have a boy born in a year not divisible by 5 and with no dimples ;-) Seriously though -you may have a boy! Plus, I would wait until the 4 month old is 2 and running around, having tantrums, etc. I think between 4 or 5 months and 18 months we almost all experience a strong desire to have another baby because they're so sweet we don't want that "baby" experience to end! Wait until you have a 16 year old girl wanting to drive everywhere and go out with boys and friends every night and an elementary girl with elementary activities and fast approaching "tweendom" AND a toddler before deciding if you really do want another! And, you also have to realize that if you have another, when that one is a baby, you'll be thinking "Hmmmm, I don't want this baby stage to end, should I have another?" You have to stop sometime!
