Q.H.
Find a good daycare with license to handle babies and toddlers. You will always have some issues with nanny or babysitter because they all have their own ways of handling children which may baffle you or even upset you from time to time. If you keep talking your nanny about the same issue(s), she might quit her job to take another job before you can find any replacement and take time off your job.
A reputable daycare has supervisors monitoring the situation for caring little ones, firing & hiring nannies who are screened for qualifications that you don't have to do the administrative work, and reporting to you of any unsual behavior of your child. Of course, such daycares are not cheap.
