When the parents come back to the house, the babysitter pretend to be nice to the baby. The baby can not speak properly yet, so the parents can not understand what happens to their baby. Even if the parents think that it is good that the babysitter takes care of their baby instead of them, this decision caused a big problem for some families. When they grow up, they will not be able to adapt the society. All parents can not practice day-care by themselves because they have to work to live.
Some parents choose to work and have a career rather than to take care of children.
Even though they have a freedom to work and have a career, their children are very precious for them. When they know that their children are suffering form something, to save their children should be their priority. Children who feel the parents affection by taking day-care from their parents will be able to give people peace and create a just and good society.
