Ds is 17mo, he has been walking since he was 10.5mo. In the past few days, I have noticed him starting to walk on his tip toes. Last night it appeared to be just one foot, so we thought perhaps he'd twisted his ankle or something. He wasn't doing it this morning, but this afternoon is doing it again, but on both feet.
He's not doing it all the time, and when he runs, he is putting his heel down.
Any advice? He's not in any pain, and I have manipulated his foot about a bit, he didn't seem to wince or anything, he just thought I was tickling him.
