I know this section is often a bit quiet, but I could really, really do with some help from anyone who gets this. I have lots of lovely straight friends, but I'm really lacking in other lesbian mums to talk to. Those we know who have children are mostly in a different situation (either they adopted together, or they have children from previous relationships).
I'm a non-birth mum to my DD who is 2. My DP is her biological mum. We've had huge problems with DP's family, especially her mum, who is (frankly) awful and constantly undermines both of us, but especially me. Lots of calling me 'auntie' and pretending it was a slip of the tongue and lots of nasty comments otherwise.
My real difficulty is related to this (in that I see where it comes from as a family dynamic in my DP's family), but my DP is actually pretty unsupportive. I feel really sad writing this. She was excited to get pregnant but found pregnancy unexpectedly hard, and she had a horrible labour and PND. I did and do feel very sympathetic, but I also feel as if one result has been that she treats me as less of a mum than her. She'll never stick up for me to her family, and she routinely does little things that undermine me, like going against a decision we made about our DD, or simply ignoring my perspective. She will always be the one to hold DD, pick her up, etc., and that becomes self-reinforcing, in that now, if I am with DP and try to pick up my DD, she'll reach out for my DP instead. When we're alone together, DD is just fine and very affectionate (I'm the SAHP).
I'm finding it increasingly hurtful and hard to cope with.
