But why? Why don't babies want to play in the grass? There's a relatively simple reason: Grass can cause a baby to experience sensory overload. During the first few months of life, a baby's nervous system is getting tuned up, developing quickly in a way that makes sounds, sensations, and sights intense and jarring.

Do babies react to grass?

"The prickly texture and feel of grass is far different than softer and more comfortable feeling of carpet, tile, and wood surfaces on their feet, hands, and body, so babies are often scared of it," notes Gina Posner, M.D., a pediatrician at MemorialCare Orange Coast Medical Center in Fountain Valley, California.

How do I get my baby used to the grass?

Don't worry if the sky is overcast — you can still get a day's worth of vitamin D in about 15 minutes. Depending on your baby's age, you can keep her up in your arms or let her down in the grass for some hands-on exploration. Sit with her at first as she feels the cool ground.
