Rough night

We took Lily to visit my husband's family tonight. He has a younger brother (A) who is only 7. I left the room for about five minutes and returned to Lily in her swing with A standing next to her singing "You're a little baby. You are adopted. You don't have a mommy. She is not your real mommy." I lost it; my face turned hot and tears just spilled out of my eyes. He's a child; I know. And when his mom and I realized what he was singing, his mom was horrified and did take him back into his room for awhile. She told me she talked to him about it, and here's the thing, he LOVES Lily. He's so proud to tell everyone she's his niece. I know he doesn't even really know what he's saying and he's probably really just interested in the whole process, but, I'm still shaken up a bit. I didn't mention anything to my husband because I don't want to upset him. So I'm letting my sadness and fear out here. I never want her to hear that again, but she will. I know she will hear things like that from people who don't understand. And I love her so much and I feel with my whole entire heart so deeply that she is my daughter that it breaks my heart to think that even though she's only a baby that she has heard already a voice tell her that she has no mommy and that I am not her mommy.
I am going to hold my baby now. Happier posts tomorrow; I'm sure.
