no harm but it may be better not to used the flavored type. use the mentholated type that does not taste very good and this may help curtail his obsessive use. remember you can help him control this by limiting how often he is allowed to apply it.
can you use too much chapstick? . my 4 year old has adhd and ocd. she feels like she has to have chapstick (she calls lip gloss) on all the time. she applies it several times a day and has fits when we don't have any. will this cause harm and if so what should i do?
