Hi Steff,
First, it is hard to interpret a dream without talking to the person. Everyone has a different meaning for things in their life and which represent different things.
Your brother, I am assuming is someone very close to you. It could be a natural brother or someone else. It seems that you desire a type of partnership. A parentship or something that we are about to embark upon is the representation of a birth. So it could be that God is telling that through someone that is close to you will help or you two together will birth something. What ever you gift or talent God is about to open a door.
