dd, who will be 3 in feb, has been diagnosed as shortsighted, possibly more than 200 and may need to wear glasses. can anyone share their experiences on this? am feeling like a bad mother. doctor says it's likely to be hereditary, as me and all my siblings are seriously short-sighted but i only started wearing glasses at 8.so i feel 2 is really young!!and how on earth will i get dd to wear them? and will i need to keep getting her new ones every week? as i'm sure they will keep breaking...
