(I’m tired, so if this doesn’t make sense, I apologize in advance)
I have read that you shouldn’t use antibacterial soaps because they not only kill the bad bacteria but the good as well and it doesn’t give your body a chance to build up it’s own resistance to the bug. I dont EVER use these soaps, we dont use hand sanitizers, we’re not anal about washing our hands, etc... and my girls (3yo and 1yo) and I hardly ever get sick.
here’s just a few articles that I found, but if you ’google’ something like ’should i use antibacterial soap’ ’stop using antibacterial’, etc...you’ll see that there are tons.

one more thing, if you (or your children) take acidolphilus/probiotics (ESPECIALLY when taking antibiotics), it will help strengthen the immune system and hopefully protect them from catching every bug that comes around. they even make chewables for kids.

best of luck!
