OMG! my son did not walk until he was 17 1/2 months old.....and even before he could walk he knew all his letters and sounds and then was decoding by himself by the time he was 3. our PT seemed to think he was delayed in walking bc he didn't like how walking felt. since he went on to become a toe walker.....i mostly agree. i also thought that once he started walking it meant he was typical. i guess i was wrong. ???
