Have posted this before, but my 21 month old ds is toe walking. He has walked since he was 10 months old, but I am noticing it more and more. I was under the impression it was reasonably common, but everyone I ask has never experienced it. I would say he is on his tip toes half the time, and it happens more when he is barefoot.
Am waiting for the HV to call, but my friend who is a HV is not concerned as is able to put all his weight down.
I am the anxious type, so be gentle.
