Everyone has an idea how hard single parenting can be. Parents in committed relationships can have a hard time with children, but they always have someone to lean on. A single parent does not always have that option and they often find parenting more stressful and challenging than those that have a spouse at home with them. If you are married, enjoy the help that you have and remember that there is always a chance you could find yourself a single parent some day too. Think about some of the single parenting issues your friends and family members may be going through and help them when you can.
One thing that most parents get is a break when their spouse comes home. Children eventually go to bed, but that does not mean that a single parent has time to themselves. One of the biggest single parenting issues that parents of younger children have is having a few quiet moments of sanity to do something that they enjoy without the company of their children. This does not mean they do not love their children. All parents have to have those quiet moments. If you know a single parent, offer to babysit once in a while and insist they go do something for themselves other than chores or errands.
