My baby cries every time he turns his neck, is he okay?

No. Your baby needs to be seen by your pediatrician. Some babies have torticollis: a condition where the neck muscle is a little short or tense. Physical therapy helps this a lot. It is hard to tell without seeing the baby, so please make an appointment.
No. It is not normal for your child to cry whenever they move their neck. They should be examined immediately to rule out a serious condition, such as meningitis.
