My best advice: learn to say "no". Explain to the ones who comprehend that you're really busy...and that they need to help YOU. Too often we Mom's put ourselves last. I had to learn that when I went thru school. My three girls were ages 8, 11 & 14 and hubby was deployed overseas. Usually I was the taximom, maidmom, chefmom, entertainmemom ect.
...I sat them all down, stated the facts and stuck to it. I made up a schedule, everyone pitched in. My 8 y/0 learned to load the dishwasher, take out the trash, start a load of laundry, make her own bed ect...and the two older two really took on alot more responsibilities. For their activities, practices, games ect...I begged & borrowed for rides. I just explained that I was in nursing school
and needed help. Helping is one of the foremost characteristics of human nature. Usually once you ask, people are more than willing to help. Once I finished school I returned the favors! Don't be afraid to ask, let your honey know you are fed up and need help, NOW.
Best of luck!
