DS has had a blocked tear duct since birth. The GP won't do anything about it and he's 9m now and every day he has a constant gunky eye. The HV said to gently rub it so that it clears and it works but it's honestly constant! My older child had this as well (in exactly the same eye) but it cleared up because she cried so much in the first 6 months (reflux baby). Can anyone recommend anything to help?
