Since folks seemed impressed, yesterday, that the Goob knows what a triangle is, I am going to take a moment or three to gloat.
I have always believed that since it's impossible to guess what a child will understand or remember, it's best to dump all the information you can on them, and hope for the best. Better too much than not enough. Plus we talk to her with real words instead of the 'oogoo geegee' stuff that many folks use with babies.
So. The Goob knows her colors, and her shapes (including exotics like pentagons and diamonds). She can count to twenty, backward from ten (usually during rocket launches), and seems to 'get' what numbers are for. We're gradually working on recognizing written numbers, and learning the alphabet. She can sing the ABC song when she feels like it. Lately she's been into learning opposites; open/close, up/down, etc.
I would love to think she inherited this intelligence from us, but my hand feels like someone's hammering a knitting needle into it after weeks of doing things I knew I shouldn't. And the husbeast just cut through an extension cord with a hedge trimmer.
Must be luck.
