January is the coldest month in Columbus, and as you see, we can only play in home. But this does not affect Richard's growth at all. He can sit for a while alone, and his leg is strong enough to support himself so that he can exploit the whole living room by his walker. Actually, he prefers the walker rather than in people's arms thus he can have better control of himself.
Eric learned lots of stuffs in this month. He recognized all 26 English letters, 10 numbers, arithmetic operators, and many colors like green, red, blue, yellow, purple, etc. And he becomes his little brother's best friend: Richard loves to play with Eric!
