Infant care should be specific to your child. Find a provider that will work with your child solely. For example, if there are several infant care providers in the building, having one that works with your child each day is important. This helps them to know what's normal and what isn't.
Infant care is more expensive the smaller a child is. But, there is a reason for this. Infants, especially very small ones, require much more attention and physical contact. As your child gets older, the rates for their care are likely to drop off to a more affordable level.
