Hi Allie--
My family are a distant memory to me at this point, as I have no contact with the ones that remain. In that sense "harmony" has already been achieved. So I am not sure how to interpret your reading...? I do have a niece and nephew whom I would like to meet some time, but that will definitely not be possible until they are adults.
AS FOR YOUR CARDS... My sense is that the chariot has something to do with a bit of apprehensiveness regarding your upcoming delivery, but also a will and determination to get through it all and deal with any problems that come up along the way. The Daughter of Cups (Brigid) is a female energy that is peaceful and is known for having strength of character. The Son of Stones (Chief Seattle) is a spokesperson for the connectedness of all creatures in the web of life, someone who has the bigger picture and thinks ahead to the effects his actions have on the next seven generations. Those could be qualities in yourself that you can call on, or others outside of you who represents those kind of energies.
I imagine that bringing a new life into this world would make you think deeply about your place in the universe. It's such a primal experience. I hope it all goes well, and that you have a lot of love and support through the process.
