I'm not a Daycare owner but I used to work in a Daycare.
When I worked in a Daycare we mostly would use and recommend Pampers Diapers or Huggies Diapers.
However we would use whatever the parents brought to us for their kids.
But most kids in the daycare I worked at wore Pampers Baby Dry, Pampers Cruisers, Pampers Swaddlers, Huggies Snug and Dry, Huggies Little Movers Diapers.
I also have personally used Dollar General Gentle Steps diapers with my own kids now and they are a good quality cheap diaper.
If I was working in a daycare now or owned a daycare I would recommend to parents if they needed a cheaper diaper that compared with Huggies or Pampers to use the Dollar General Gentle Steps diapers.
