Incidentally, one thing that helped my son’s stress levels (which in the end we put it down to) was that he was clearly a child that needed routine and to KNOW what was going on each day. He got very distressed one week at school when there was a special activity which involved him being in a different classroom with different children.

The teachers were fab and went out of their way to make sure he was given 24hrs notice of any changes (such as a teacher being away on a course, etc) which was really helpful and he settled much more quickly after that.

My HV also suggested that rapid blinking can be a sign of problems with eyesight (as you blink the way the light hits the back of the eye changes, so can be a way for them to try to focus). We did take him to the optician (they don’t need to be able to read – they have symbols for the littlies) and he wasn’t short sighted at the time (he did later become short sighted, but not totally surprising given that me and hubby are both short sighted) – but might be worth popping into an optician if you can, if only to rule it out?

But I can’t really say anything “cured” it for him other than age and confidence.

Just to reassure you that sometimes it can mean absolutely nothing, just be a phase they grow out of and not be anything sinister. I hope the same is true for your little man
