I'm really trying to "enjoy" these last weeks or even days until Sophia is born but I'm so miserable i almost feel guilty because I'm not sure how I feel about this I don't want my son to feel left out , will I be able to give them both the attention they need . Will I snap out of this funk? What's wrong with me are any of you other mommies experiencing this ?
