Did your neck and shoulders get sore after having a baby?

My wife recently had a baby, and I didn’t realize how much feeding, holding, and constantly looking down could affect her neck and shoulders. By the end of the day, she says her neck and upper traps feel tight. Hot showers help a little, but she doesn’t always have the time. I’m wondering if something simple like the neck massager with heat would help her relax while sitting on the couch. I’m not expecting it to fix anything medical, just something easy and comforting. Has anyone used one postpartum? Was it actually helpful?
