As a parent, you know it is your responsibility to make sure that your child is properly taken care of at all times. In fact, you might only trust yourself when it comes to making sure that your little one is fed, played with and watched during the day, but the truth is, you probably can't watch your child all the time. You might have to go back to work, which means you will have to make other childcare arrangements during the day. Even if you are a stay-at-home parent, you might need the help of a nanny so that you can get household chores and errands done and so that you will have a bit of time for yourself. Regardless of your reason for hiring a nanny, you need to keep a few things in mind in order to keep your child safe while he or she is under someone else's care.
