DS is still not walking at 19 mos. I'm wondering if he has hypotonia. OK, so I'm extra paranoid about him because DD has PDD, but I'm wondering if I should get him checked out. He belly-crawled at 7 mos, but didn't sit until 9.5 months. Pulled up at 11 mos and has been cruising ever since without the slightest sign of actually taking steps on his own. Can walk holding my hands but is very very wobbly. Also has very high arches to his feet.
Am I just worrying unecessarily or should I hassle my paed?
