Theres a thing call the Uncanny Valley, its easy to look up on Google.
In brief it is the feeling of unease when we see something that looks very human acting in a non human way, or conversely something very non-human acting in a very human way
Robotic dancers are in there, Dolls are definitely in there, to name a few examples.
It sounds like you're encountering this phenomenon, and it's very natural. We all experience it to some degree, but what each person considers as their tipping point as diverse as the valley itself.
Armchair psychology lessons aside, as other have said, give it a couple of days. You're loosing nothing at this point to give it some time. If it doesn't happen, it doesn't happen. You wont be the first. I've actually had a doll I didn't bond with and after a week she was gone to a home where she is loved to this day.
One small hint to try. Move her eyes so she isnt looking dead ahead. The 1000 yard stare is what makes most dolls look uncanny. Just a little to the left or right is all thats needed
