Christian is has been really unsure of grass in the past. You can set home down and he immediately picks up his feet and basically tries to keep as much of his body off the grass as possible! But I have slowly enticed him to warm up to the grass by playing with bubbles, a favorite for sure! Now anytime you point to grass he says "bubbles!"
It is so fun to watch your child learn and explore. Everything is new and an experience! The simplest of things, like grass, is fascinating and I love to see his wheels turning as he touches, smells, looks and yes tastes this foreign thing!
