Rainbow babies

Lauren
Any mammas of rainbow babies here?
We lost our first son almost to the day of when we got pregnant. Our second son's due date is 1/31/2017. Hoping to give my dad a grandson for his birthday on 1/25. Our son will have each of our dads middle names which are our granddads first names. We are not telling anyone the name until he is born, I cannt wait for the shock on their faces!
