@IMightBeAParent I get the thing about feeling confused about how to feel about the mums thing. Our society is so set up to have this single almost sainted image of 'The Mother' that is portrayed to be one person in one specific way. However, as an adopter you end up coming to understand that multiple things can be true and yet opposite. You hold several realities in your mind. I'm in a same sex relationship, and so who got to be the mummy/mama issue was something we had to discuss and come to terms with very early on. Our children would always have at least 3 mums, and we knew they would have to deal with the duality of that as a matter of course. The reality is that they don't- they have more, because they have us two, birth mum, and a foster mum each. Our household buys many mothers day cards! But that's because each of those women played a very important part for our children and mothered them in different ways. If you can let go of the concept of a single entity being mother, suddenly your capacity to understand the nuanced and complex feelings about adoption and family is enhanced. As a society we seem to have a better view of multiple men being able to fill the father role for some reason, with stories of step dads and uncles stepping up to the plate to be "real dads", but as a society I feel we struggle to do this more with mothers. Obviously I blame the patriarchy ;) but honestly, as a queer couple, we have had to reckon with that as a matter of course, and I can reassure you the kids take it in their stride. Having more mothers doesn't diminish our role for our children in the way you might think. Its not like its pie, that the love they have ilis finite and can only be given in chunks, so more for one means less for others. We don't think the same way about other relationships- just because you have 4 grandparents doesn't make any one of them less or more than another. Their actions might affect how close a relationship they have with you, their choices, their personality may impact to a greater or lesser degree etc, but they are not any less a grandparent because there are more of them. You love them for their actions.Its important to note that they see us totally as their mothers- they might hate us, they might be angry with us, they might rail against us, but we are their mums because we do the mum things.
Secondly, you don't give the children power to decide your role. In brutal terms, it doesn't really matter what they want, they don't get to choose you. Social workers and judges did, so in the same way a bio child gets to rail against the unfairness of having their bio mum as their mother, they get to be cross with you about you being their mother, as per the injustices of their teenage life. I may not be their only mother, but I am their mother whether they like it or not, so they get to love me and hate me in all those ways.
Also, they didn't get to choose, but I did. I chose to be their mother, even though I didn't have to be, and so their words and actions can't take it away from me. I do the mum things, and to be honest they can like it or lump it. I'm still going to be there, turning up at their plays, doing embarassing dances and telling them off for being daft. Unfortunately their birth mum can't/won't/doesn't get to do that part of mothering them, but she did get to give birth to them. The kids can can like or lump that too! She did the part where she carried them, gave them life, and loved them from where she was at. It wasn't enough at the time to give them what they needed, but because she did those things yes, she also was and is their mother. This may not apply to all situations, because all BP situations are different but in ours I make people (particularly professionals) speak with respect about her because she is the mother of my children she just had her own heavier burdens to bear. I won't have people who don't know her speak judgementally of her because she gave my boys life, and in her own way, tried to care for them. She didn't have to. I also won't ignore her. If the boys themselves choose to do so, that is their call, but as much as we can, we try to make sure that the children hear us speaking about her with compassion and we advocate for her in the best way we can. We are forever tied to her now and want the best for her and the boys. This will be different for other people, and we didn't expect to feel this way, but I hope that I'm explaining it in a way that shows you that there are lots of different ways to feel and none of them are right or wrong, but some of them require you to think outside what the "normal" values of society are and what people say you should think or feel about being a mum. Maybe you will be angry with BP and want to cut them out.... but then again, when you learn a bit more, and see examples of how families can work when you put aside certain social expectations, maybe you won't. And you are allowed to sit with the weird feelings that might give you and change your mind over time one way or another too- I know for sure that the way I thought I would parent, and thought was good parenting, has changed based on what I've read on this forum, the adoptive families I've met and the family setups I've learned about. Throughout time, families have deviated from the traditional mum dad 2.4 kids model, even if that's not what people want you to think, and once you start accepting this reality, your mind can be opened to a theoretical possibility of what options for contact can look like.
All that being said, whether other grown up people treat you like a "real" mother is different- people make ignorant comments (particularly about mothers) all the time. However they do that about literally anything and everything, so adoption is kind of one of many things they could comment on. They do the same if you are fat, smoke, drink, do or don't breastfeed, go back to work, be a SAHM, have a religion or are different to them in any way, or so it seems to me!
In the future, our kids may want to get in contact with BPs in some way, and as PPs have said, we can be cool with that because it means they get to know the real person, rather than a nightmare or a fantasy. But we can mainly be more open to it because we have discussed and thought considerably about what being a mum means, and decided a point from which we were their mums, and just had to act as such. From the moment we were approved at panel for our boys, we were their mums. We were committed to every part of them, the good, the bad and the ugly, and they got us, the good the bad and the ugly. We are learning on the way, and by goodness we have made many mistakes, but that's kind of what families do, right? If you do the mum stuff, you are their parent- social workers come and go, psychologists leave and don't come back, teachers move on, BPs can waver in contact, and yet you are there for your child. It is that bit that makes you their parent, and that bit that they will feel.
I know this post has been long, and I debated writing/continuing to write it, but you struck a chord because you put into words a fear that I think I felt before I adopted but never really knew how to express. I hope it is reassuring that, for me, so far, those fears have not come to fruition, but I definitely did have them, so it's not unreasonable to be thinking about these things and considering your options.
