Hi girls? How are you? I noticed that when my daughter cries her lower jaw shakes ? I didn't notice it before because we weren't letting her cry. At three months old when they got massages, she cried for one day then the masseuse noticed the jaw. But she said that it can happen up to four months old for little ones. I started worrying ? Has anyone had this? Please tell me, I'm worried but everything seems normal and there is still some hand tension ? We're going to get another massage to the neurologist, we booked an appointment.
