If your child’s teacher has mentioned that they fidget, slump, or struggle to keep up with copying from the board, this is worth reading.
There is a primitive reflex called the STNR, the Symmetrical Tonic Neck Reflex. It plays an important role in early movement development, helping babies prepare to crawl. It should switch off before a child starts school. When it does not, the consequences show up in the classroom every single day.
Every time your child looks up at the board, their legs respond. Every time they look down at their book, their arms respond. Sitting upright and still is not automatic for them. It is exhausting.
A retained STNR can look like slumping or W-sitting, difficulty copying from the board, fidgeting that the child genuinely cannot control, poor upper and lower body coordination, and significant tiredness by the end of the school day.
At Think Thrive, I use the INPP method to assess and support primitive reflex integration in children across West Yorkshire. If any of this sounds familiar, I would love to hear from you.
