Introducing orange color

This week, mommy introduces him orange color.
Still, mommy has no expectation for him to remember all colors but mommy believe his brain is absorbing everything.
Since, Chinese new year is coming soon, mommy got idea to let him play with oranges

He can touch, sort big and small, stack like snowman and even throw like a ball
And mommy provides sensory box with all orange color items and he loves to stamp on his own body hahaha
