Liquid hand soap tends to be easier to use for little kids, and many BIG kids too. However, you are constantly refilling the bottle.
I use refill bottles of liquid soap, but take an empty foam soap pump bottle. I find everyone seems to enjoy the foaming soap.
1. fill 1/8 of the foam soap bottle with refill the liquid soap of your choice
2. fill the rest of the bottle with water, leaving about a finger width remaining at the top of the bottle to make room for the dispenser.
3. Put the dispenser in the bottle and give it a gentle shake to mix soap and water combination.
You will save a lot of money with every bottle refill and you won’t mind all the “soap” the kids will go through.
