Re: SEVERELY chapped lips. What to do?
Most chapstick-type products are proven to cause drier lips (whether from the ingredients or from kids licking lips more often due to the gloss being there). I would cut that part out.
Agree with the lanolin/lansinoh type product (or vaseline, but it doesn't stay put as well). Get the lips wet first, then apply the lansinol (so there is moisture to get sucked into the lips without drying them more), then repeat throughout the day.
As a PP mentioned, you'll likely need to break your son of the lip-picking habit, too.
