From most of the post that I have seen most kids my girls ages and even some that are younger are soooooo far ahead of my girls. My 5 yo does not know how to read, can not recognize her numbers or letters, does not write, and only knows basic shapes. My 2yo can count to 2 and will not count higher and knows some shapes and colors that is about it. Am I failing them ? What are some things I can do to get them more advanced?
