DD 2y5m has a slightly lazy eye when she gets very tired - usually for no more than 5 minutes before she falls asleep. She did have this as an infant as well, for slightly longer periods, but I wasn't too worried as I figured her eye muscles were still learning what to do. DH also gets a slight squint at times, also generally when he's very tired, so I'm guessing this is just a trait she's gotten from him. It's not there every day or anything, just occassionally. Is it worth making an appt at the GP or would you just leave it? If it were constantly there I would of course, but I'm not sure there's any danger in it if it's only present sometimes? Any experience?
