Baby fever/jealousy

My husband and I have been talking about babies.. he wants one now but with our current jobs it just isn't realistic. We decided we would start trying next fall. Well, we just found out his brother and sister in law are pregnant. Happy for them but also finding myself extremely jealous at the same time as their entire family is making it a huge ordeal. Just need to vent here so my jealousy isnt apparent when we see them next!! It's so hard to wait!!
