I have a six year old daughter,(June she be 7) I am a worried mum as teacher says she is behind in most things I have busted a gut trying to bring her forward as some times I think maybe it's my fault some how, as I have a 10 year old who is a year above her age in all her work. ( I seem to compare my oldest daughter with my youngest with what she did at this age.) I was told last week that maybe I should take her to a Behavioural optometrist, she does wear glasses and as a regular check up I'm also taking her this week to dr's to check her hearing. (incase she as glue ear.) I have been in touch with one and they are quite a bit expensive. Are they any good, and what do they do?
