It is normal to feel some sort of anxiety the first time you leave your child with the nanny. Try not to stalk your nanny with phone calls throughout the day. You can arrange a time with your new nanny whereby you can both communicate on how the day is going. DO NOT STALK HER WITH PHONECALLS, every other hour. This can typically offset a bad start in your relationship, you have to reassure yourself that you did make the right choice and try not to impose your insecurities on the nanny. Constant phone calls throughout the day tend to make the nanny feel that you have no confidence in her and can raise a question on her part of whether she made the right choice of accepting this position.
