PLEASE HELP Why One Parent Should Stay at Home

It's a busy world, and parents have less time than ever to spend with their children. One solution for this problem is having one parent stay at home. Being primarily cared for by a parent at home benefits children for many reasons. Just as infants and toddlers benefit greatly by being cared for by a parent at home, so do older children who thrive under parental supervision.
Parents who stay at home can spend hours of quality time with the children every day. In contrast, working parents have less time each day to spend with the children. The time spent at work is time spent away from the children. Add a daily commute, errands, grocery shopping, and housework to the list, and working parents have even less time to spare at home. The already-tired working parent has less energy and time to bond with his or her children.
A child with a problem or concern is likely to ask for advice only from parents with whom he or she feels a strong bond. The parent who stays at home has time to educate the child and help him or her overcome academic problems and other issues. According to the U. S. Department of Health and Human Services, children who spend more time away from their parents' care showed more behavioral problems. Young children at daycare received less attention from adults compared to children who were cared for by a parent at home.
More families should consider the option of one parent staying at home. With a few economic sacrifices and compromises, many families can afford to have one parent stay home for a few years to raise the children. Parents should consider their children's futures. Their children should have at least one parent stay at home. After all, a price tag cannot be put on the value of successful and satisfying parenting.
