Big smiles at 2 days old...I have never understood the idea of an older sibling resenting the entrance of a new baby to the family and why people seem to expect it now days. I get frequent questions about it when I am expecting, and lately from many young mothers expecting their second. We have never once had a problem with it and although there is that slight chance we have gotten "lucky"... I think after seven babies that it's unlikely. I have had such the opposite experience and seen it as well in the families I know that I have come to believe that sibling jealousy is very much up to the parents. (I've also watched plenty of TLC's A Baby Story while on bedrest in the past) and learned how not to do things. The best advice I can give to Mommas welcoming in subsequent children begins with not allowing that fear and doubt to even find a place in your mind. God says children are a blessing. So they just ARE a blessing to their siblings.
Children are a gift, and who benefits more than their siblings? Start right by not believing the lie that a new baby is anything but the greatest gift to the older siblings.
Like I said though, I feel it is more a parent induced problem than anything. In this case, like many, prevention is the best medicine and I encourage other mothers to look ahead with absolute JOY and anticipation of the loving, protective and giving relationships that all her children can have. Train early, build up your child's anticipation by calling your pregnant bump "her baby" or "his new little brother", emphasizing what an important honor it is to be a big brother or sister and how much you'll need them! I have let my four year olds change newborn diapers with baby safely on the floor. It is REALLY fun to watch! :) I find they take to it naturally when they do not sense fear or expectation of jealousy on the parents' part.
We are truly blessed.
