Hello and welcome to the forum. Thanks for your question. It is never a bad idea to ask your child's doctor about something you are concerned about. If you are sure that the sagittal suture closed properly during infancy, then I would think this is the common tenderness some kids exhibit with such activity as hair brushing. There are a lot of nerves on the scalp that can be activated with that type of action. If it seems much more than your typical child, there is also something to look into called sensory processing disorder. Kids with this issue often feel things in a more extreme way and while others can ignore it, the nerves receive signals of pain from that area as an overreaction to stimulation. It is what occupational therapists call tactile defensiveness which really just means touch bothers them. htthttps://thesensoryseeker.com/2018/01/24/hair-sensory-issues/ps://thesensoryseeker.com/2018/01/24/hair-sensory-issues/.
Does your child have any other issues with touch or textures or fine motor control?
Hi DaddyDad. My own son has sensory integration disorder and lots of issues around texture and food and the way clothes feel. Tactile defensiveness is hard to understand unless you have it, I suppose. But even I can be greatly bothered by a turtle neck. My son acts like certain things hurt him when I'm like "how could that hurt". :>)) The OT my son saw for long time did something called 'brushing'. I can tell you how to do it if you are interested. We had a soft brush like what they use on babies in hospitals and you brush in a pattern on the arms, hands, legs and feet. I guess the theory is it helps the nerve endings. But the best thing we did was Occupational Therapy where they did something called 'heavy work' which directly soothed my son's nervous system. The effect could last for several days. Happy to chat more if you'd like!
