Leaning baby?

Judith

I noticed that my 4 month old baby is usually leaning to the left? Whether it was in the jumper, bumbo, sitting in our lap? I googled it, of course, a first time mother’s worst enemy and also best friend, it mentioned Torticollis. Idk. Should I be concerned? Does anyone else’s baby does this or has gone through it? How do you fix it? He also isn’t using full range of motion in his neck.
