My two are exactly 15 months apart. As the other moms said there really isn't much you can do to prepare your 1st born. We did the same as others and talked about having a new baby and read some books, but overall at 15 months they really won't know much of a difference if you can just try to continue to provide them alot of attention...hopefully you have some family and friends that can help as you care for your newborn. I was overly concerned and my pediatrician said your oldest will never know the difference and he was right. My daughter doesn't and won't ever remember life without her little brother and vice versa...our son won't remember a time without his big sister in his face...ha! It will all work out as you said. I'll tell you its hard at the beginning b/c you'll be so tired but in the long run you will LOVE having them so close together. To watch my two interact is so wonderful and such a blessing. Good luck to you and your family!
