My 7yr old still writes many letters backwards. She can't tell a lower case b from a d. Her numbers end up backwards often too. She also puts her shoes on the wrong feet half the time. She says she doesn't see the difference. She reads some words backwards like on is no or sounding out a word from right to left though she's been aware of left to right for many years. Then she shakes her head and starts over. I never worried about it before but I am starting to because it seems like she should get it by now. When do you really need to be concerned about this? Is there anything that helps it or will she eventually get it?
