2.8 yr old squinting

[diet7up]

I've just noticed my DD keeps squinting, not all the time I noticed it at the weekend, then last night when she was watching TV, but this morning she wasn't doing it?
Looking online i found some info that says it?s nothing to worry about and other websites say to get it checked, has anyone had this with their kids?

its best to get it checked as it could be a sign of a problem with her sight. I noticed a squint in dd at 18 months old and when it got checked it turned out she was long sighted and needed glasses. She still has them now at age 9. I referred dd via the hv or you could try your gp. DD was under the care of the orthoptist at the local hospital until the age of 7 at which point she was discharged to the care of the normal high street optician.
