Try not to see your time as free time, you do not always need to seperte your time into catagories e.g work, housework,kids etc. For example invole the kids in some of the things you do on a day to day basis. Gardening is a good way for families to spend time together whilst getting chores done, educating children and just time together. If your kids are quite young they will love to help you with the housework. Most of the time children are happy just to be with you doing simple things rather than having to set out specific times for them.
