I had "the talk"

Thanks to some very sage advice for Dickons and some other adoptees, I've been trying to figure out the right time to tell me DD the man she thinks is her BD (my cousin) isn't her BD (dna showed this when dcyf began moving towards tpr for her mom) there was never a good time. I kept reminding myself i didn't want her hearing this as an adult and feeling i lied to her for her entire life Last night was the first shot (btw, shes 7) She's a bit cagey about things she heard before coming here.. She won't say things she knows she wasn't supposed to hear, so sometimes its a guessing game. I have been looking for a way to age appropriately add the information for over a year. There never seemed to be a good time. Yesterday we were talking about who we might see in Maine next week she's sooo excited!! She wrote her cousin E a love note yesterday at school). I mentioned she might meet DH's other sister K. Which led to talks of half siblings. I explained her brothers in CA are half siblings because they have another dad. She kept saying J2 was her whole brother because they have the same mom. She said the three times, never saying the have the same dad. Even after I pointed out she has the same mom with her brothers in CA. This was 20 minutes before leaving for cheering practice. I didn't want to get her wound up then drop her off. So I stopped talking. She asked me why my face looked funny. I told her I was trying to figure out the right thing to say. Then I said "you know you have 3 dads right?". she said "huh?" me: did you know, when mummy and daddy j broke up, she had a new boyfriend? jaz: yes, M me: no, before M* jaz: ok me: well he and she made a baby, you.. but mummy wanted to make sure you had a family so she and daddy j got back together. that way you'd have a dad a mom and a brother** jaz: how is he my dad if i never met him? me: it takes one man and one woman to actually make a baby.. so in some ways that makes J2 your half brother too jaz: but we lived together me: right - he's your half brother and your whole brother jaz: that doesn't make sense.. how can he be both? i tried to back pedal since it seems important to her that J2 is "really" her brother. different that the brothers in CA. thats true, unfortunately, we don't have words for grades of connectedness like that. then she got hyper again.. not sure if its the fact we had just prior talked about seeing her cousins 3 times next month or if it as the information. i asked if she wanted to watch tv for a few minutes. she said yes, then went to her room and read "dog heaven" until it was time to leave * i couldn't remember the guys name in the moment. fortunately she never asked ** a bit of creative twisting of the facts.. but its really all she needs to know at age 7. i did point out that daddy j loves her very much
