Am a germaphobic "squatter" and would
never sit on a public toilet seat unless I were on death's door!

For those brave souls who enter behind me and actually SIT, I do take care to avoid peein' on the seat... but I also KNOW others before me were not so kind... so again, no sittin' for me!

For our kids: Boys came into the women's bathroom with me until about 8. Then I would make sure the men's room was empty and stand watch until they were done. Now, our oldest can take the younger one and they go together - but NOT alone!! Even now, we still make sure the men's room is empty and stand watch. If the younger is with me alone, I will still bring him to the women's (making sure there are no gals present) - unless the men's are single stalls, in which case he can go in alone and I guard the door.
I watched a HORRIBLE documentary about a darling 8 year old boy who was killed by a teenager in a McDonald's bathroom. It was truly one of the most gruesome things I have ever seen... so, our kids will have an "attendant" until they are bigger than me.
For our boys, until they were old enough to stand up and pee into the toilet without "important parts" touching, we would hold them, facing backwards, so they could pee in. When they got a little older, but still not quite tall enough, we would stand behind them and let them stand on our feet to give them that extra height.
For our daughter, we stand with her facing the rear of the toilet and hold her over (hands under her thighs, and her back against our stomachs). She can then hover over without sitting on the seat.
We do, definitely, love the family bathrooms!!!
