Nowadays, mostly both parents are working in order to live comfortable, to sustain the needs of the family and in order to send their children to a good school. However, there are some disadvantages of over-delegating task to the caregiver or to the school,  to watch out their children's manner and to care with them at home is not an obligation of the caregiver anymore (unless if one of the parents is the caregiver as as well -- or she's the one taking care of the child, mostly a mom which is often called as stay-at-home-mom) but it is the the parents obligation! On the other side, if you're delegating (should I say, over-delegating) your task to other person (or the caregiver), the effect to the children on that case is that they are more comfortable with their nanny(ies) than to the their parents, the worst case is that the child won’t go anymore with their mom and dad but they want more to be accompanied with their nannies. That’s why even once a week you must have time with your family, family bonding is needed, in order for your children to feel that you are not too far from them.

A thought of family bonding is up to you couples. You can make your very own bonding on your very own ways that both of you will be satisfied in all ways.
