I would temporarily pull the hair back with elastics as well, as reduced vision is a safety issue and I would mention if the child was tripping or bumping into things as a result of the hair. I also get the jeans thing, but not for the sake of how it looks. I have issues with a chunky toddler who almost always comes in wearing skinny jeans, and I can't get them pulled down to change her diaper, as well as she can't properly walk or climb the stairs in them. I have made suggestions to parents, but they didn't catch a clue. I don't mind the jeans if they were loose or had the crotch snaps, so I could change the diaper. My other pet peeve is unclipped fingernails. I am doing all the kids regularly at about 10 day intervals as they are hurting their friends, and I tell parents I did it as they were scratching others/self or me, and my parents don't say thank you or feel embarassed that they forgot to do it. It drives me crazy! O.K. my rant is over!
