S.P.
I am a mother of 4 children. One of my twin girls was put into glasses at 10 months also. Same reason as yours. She is the only one of the kids to get glasses that young. She is now 18 wheres contacts, but she does have to have her eyes examined every 6 months because of drastic changes in her prescription. Not sure if that has anything to do with her going into glasses at such a young age or not. It is nothing you did it just happens. Good luck.
