'hard' blinking in a toddler?

[milkyman]

I've noticed recently my 2.3 ds is hard blinking. Could it be tiredness. I don't think it's his sight.

I would have his eyes checked by an optician, even if it doesn't appear to be his sight.

It might be tiredness or that he's just found a new sensation, but his vision could be blurring etc.

He could have just discovered he could do this and it is a novelty. He could be attempting to wink.

My ds did this. Hv referred him to eye clinic in hospital. That was all fine and he grew out of it. Best get it checked out though.

Mine does this sometimes. Happened to do it to the GP, who laughed and told him to stop trying to be cute. He stopped.

Is he drinking enough fluids? I get dry eyes and when I don't drink enough it gets worse and I blink really hard!
