I was fixing some toys of my 5 year old and he asked me if he could watch the glue dry… I told him “son, that’s like watching grass grow 😒”… his reaction, “really 😱… can I go in the backyard?”, me “yeah, sure, I guess 🤦 😂”.
He’s still there… sitting on the ground, watching… asking every 2 minutes if the grass is any taller 🤣.
Go out every day with a ruler or a tape measure and take a picture with a measurement. He might not notice or remember the daily growth but after a a few weeks there should be a noticable difference if the climate of your area is still warm enough.
Oh, that’s a nice idea, I’ll do that, thanks 😊.
