I bet you don’t let your kids go to the bathroom during Mass, let alone during the Consecration. This is something that ruffles my feathers. I want to stare at them.
Never during the consecration, although I've sometimes had to take a newly toilet-trained participant to the bathroom after Communion. Anyone over age 4 has to go before Mass and contain themselves until the end.
(Unfortunately, my husband's a bad example on this, as he is on the wearing of shorts. One can't have anything ...)
