Baby discomfort

My baby seems to be uncomfortable everytime I put her over my shoulder. She’d wiggle and toss and turn. She’s lean sideways down to my breasts like, she’d do anything to not be straight up on my shoulder. I’m wondering if she may have reflux or something. She only keeps still if she’s really tired and going into a deep sleep. I thought most babies enjoyed this position 🤷🏽‍♀️
