I remember being so frustrated when Maggie wasn't hitting some of the milestones. She's supposed to be able to tie her shoes and jump on one foot and know the alphabet. Luckily, she loves learning, so the alphabet came easily and early. It's nice when your kiddo gets something down pat, and you can really see the progressing.
Another mom once told me that it's ok if they never learn to tie their shoes. Just get slipons or Velcro. Nice. And when are you ever going to need to jump on one leg? Never? Ok, cool.
Somewhere before one even they are supposed to be able to stack block. Sigh. Maggie just did not get that one. I'm not sure what sensory information she was missing to make the connections, but it did not come.
