What if the real problem with screens isn't what they're doing to your child, but what they're stopping your child from doing?
This weekend I watched my granddaughter spot her puppy across the room. The moment her eyes found him, everything changed. She started moving toward him, falling forward, recalibrating, pushing herself up, trying again. She didn't give up. She wanted that puppy too much. And when she finally reached him, that smile was everything!
As a pediatric neuro-optometrist, what I saw wasn't just adorable. It was her brain being built.
A study using MRI brain scans found that preschoolers who used screens more than recommended had lower white matter integrity, the wiring that helps children learn, focus, read and communicate.
But here's the part that doesn't make the headlines: your child's vision is the spark that makes them want to move, and the effort to get there is the whole point. Every time a child sees something they want, works to reach it and gets there, their brain learns that struggle is safe, persistence pays off, and they are capable.
A screen brings the world to the child. No distance to cross. No effort required.
The best thing you can give a young child isn't more content. It's more world. Put the puppy across the room. Let them work for it.
