My 6 month old baby has been sick this week but my mother notcied that her right eye is getting really lazy is there something I should worry about?

Lazy eye probably has nothing to do with her being sick, but you will have to address it before she gets in school. This is not uncommon, but easily corrected. If you want, talk to her pediatrician next visit.

It is a matter of surgery on the muscles of the eye that is lazy, to correct the pull.

I noticed my sons eye randomly rolling at 9 months. By 13 months he had his surgery so get it taken care of asap.

Sometimes glasses can correct this problem without the need for surgery.
