The greatest of Congratulations to you! I remember when a friend told me after they had their first baby that 'it's like falling in love all over again.'
Speaking of changing diapers, before my daughter was delivered of their twins my son in law assured us that he would be very active in the children's lives but "I draw the line at diapers. My stomach wouldn't take it."
End of story: Long before they left the hospital he was changing diapers on those little bottoms like an old hand.
