Once when my dad and I were on a fishing trip, we were devoured by mosquitoes, right through jeans and long-sleeve shirts. We put Scotch on the bites (cheap stuff, mini-bottles from an airline, remember those days), and it killed the itch completely.
Giving a teething child a dab of whisky on their gums with the corner of a washcloth is probably considered child abuse these days by the Mewling Quim control freaks Child UnProtective Services out there and a perfectly valid excuse to steal your children away and put them in the waiting hands of some poorly vetted foster perverts.
My babies like red wine.
