Baby fever has hit me bad

My brother and his fiancé have just had their 3rd child. He is a very  cute chubby cheeked little boy. He went back into the hospital because his jaundice levels were very high, so I went to the hospital to see him. After holding him for about an hour I could probably of seen my ovaries glowing with how much I wanted another kid. I have 3 boys now from previous relationship and I really just want to give my husband a child of his own. His ex got his kids taken by the state and I know how much he misses them and wishes he had his own child around.
