Usually, I find this difficult...mention it or not...how, when etc. But in this case I think that you must! They all develop differently and there are different spectrums of normal, but none of what you described is anywhere near normal. Go to her with information...not just giving your opinion. Do your research. Print things up on development, stages, variations of normal to show her that she needs help. Also have a contact number to give her and follow up. Someone has to help this girl.....don't make her wait until she starts school...
