Of course the final decision for your choice of child care depends on other factors, mainly the child's needs and personality, your finances and your general feeling.
Talking to other moms and dads in your area and doing some research is a good way to gain information about qualified nannys or daycares in your area. You could also walk by a nursery at, say, play time and home time and see how the children behave and how they are cared for.
Once you have weighed all of the considerations, be confident about your decision and start preparing your child and yourselves for the change. Be patient, you know what they say about new beginnings.
