If you feel like you have too much to remember, then carry around an organizer in your purse. Jot down everything from phone numbers, to appointments, to worries. That way you won't forget.
Make “me” time during the day, take a shower, paint your nails, something for yourself. If you can't find time, then schedule it, jot it down right in between dinner and pickup from soccer practice.
Write a family information binder, so If for some reason your away, or someone else is watching the kids, they will know what medicine your kids need to take, any allergies your children might have, and even the numbers of the nearest take-out restaurants.
Make a “worry” appointment. Instead of worrying about things all day long, set up a time during the day to worry. Call up your best friend, talk to your husband, or write in your journal. It will help clear your mind for the rest of the day.
Clear out the clutter. Believe it or not, a clutter-free house is more relaxing. When there is many things in a tight space, or if its un-organized, it can feel very overwhelming. Get rid of toys your children don't play with anymore, and organize the ones that they do play with by sticking them in a toy chest. It also helps to put smaller toys in plastic containers with lids, and a picture of what's inside, this can help your child learn how to put things away when he or she is done with them.
If you only have time for 3 things on your list, chose the ones that have the most impact, or urgency. This will make you feel like you have accomplished more.
If your children are old enough, have them help you. It can be fun to have your child help you prepare dinner, or do the dishes. It will also relive your stress and allow you to spend time with your children while still doing the things you need to get done. To be even more organized, create a chore chart for not only your kids, but you and your husband as well. It is a fun alternative to a formal to-do list.
