My wife woke up to find out daughter holding an empty tube of chapstick so we dont know if she ate any of it or not. There was one other time where she actualy ate a strawberry flavoured type of chapstick from what my wife has told me. This type was an old tube my wife has had for a few years that has a mild spf15 with a mint flavouring added to it. I know that as a kid that whenever we would go tricker treating we would enevitably get wax lips or wax teeth or the wax soda bottles and that stuff almost always got eaten to some degrea or another and I never got backed up but then again I was also a few years older than she is now. I googled a half dozen variations of " my kid ate chapstick " and the closest thing that came up was " my baby ate some deoderant ", aside from her being a bit cranky all day there hasnt been any symptoms asociated with poisoning so I think that the tube must have been almost fully gone.
