my 6 months old girl baby left eye lid is smaller than right one,what could be the reason and it is curable or not.

A. Actually with the picture that you have posted it doesn’t look like it but if you have any kind of a doubt about it you’ll have to have an assessment with your doctor for that with which only they can confirm whether genuinely a problem or it is just looking like this to you as of now and if there’s anything you need to do to fix the problem if they figure out something then they will tell you accordingly
