Write them down and take them with you so you won't forget. A common recommendation is one adult for every three infants or toddlers. The provider should have an open-door policy and welcome parents at any time. If this is not the case investigate further. Most providers should follow some type of schedule for the children.
Most children thrive on routine and knowing what to expect.
This is especially important for daycare done in another's home. You have a right to know who will be in contact with your child. When visiting a daycare provider look closely at your surroundings and how the kids interact. Examine the equipment for sturdiness, rust, protruding objects. If many of the kids are just standing around this could be a sign of boredom.
