My dh and I are both short sighted - his is severe. A friend recently suggested Dd1 (3.5) may be short sighted. She is always standing right up close to the TV (on the rare occasions it is on ) but I thought that that was just what children did. We tested her by asking what she could see on the screen and she leant forward in her seat before answering correctly. Are we being paranoid? How can you test a 3.5 yr old. Is it necessary to diagnose it this early? Thanks in advance.
