I noticed that my 4 month son will be bending his head to the right side and not turning to the left, he started this two days ago. After doing some research I found out it might be a stiff muscle. I did some excises to help him stretch his neck, I also placed him for tummy time, where is able to turn side to side. Also I read that babies should not be placed in the car seat to play; this causes the neck to bend to one side.
