I'm starting to think my husband is wanting another child. I mean we are pregnant now but another child after our son is born. Kinda feeling overwhelmed because he's thinking baby #3 when baby #2 Isn't even here yet. With how difficult this pregnancy has been and how difficult my pregnancy was with my daughter. I am very open into adoption and we wanted to when our son was 10 but now I'm thinking maybe we should think about adopting a child much sooner. Maybe I'm thinking to hard about this but it's defiantly something we have to talk about.
