A relative of mine, "she who shall not be named" (aka my MIL) has said this or a varriation of it since babe was born. It bugs me, intensely. She means well in general, even if she bugs me to no end, but she can be clueless. Because of how intensely she can bug me my tone isn't always so "gentle" when talking to her, so I didn't want to make an issue of her saying it, hoping it was just a baby thing she says, hoping it would stop when babe became a toddler.
Well, sure enough last week she said, while holding babe after babe had done something funny, "What are we going to do with you, huh? I think we'll keep you."

My blood pressure rose instantly, I began to interject, I'd had enough, then suddenly my FIL came in and her attention was gone.
How can she not hear what she's saying? How can she not get the double meaning of her remark? Am I off here, over sensitive? Any adoptees want to chime in?
