Hi
Congrats on your baby. Wanting to be held and not sleeping alone is perfectly normal for human infants, so please don't think there's anything wrong with her, nor is meeting her needs the wrong thing to do.
Is she feeding well? What are her symptoms for the reflux? Does she just want to be held - do you use a sling or carrier to help settle her more easily?
She's not grumpy, she's just communicating with you. She's a good talker, hey? That's going to be really good for her when she's older and needs to stick up for herself. Hang in there.
