S.M.
You surely have your hands full! Just keep reminding yourself that it WILL GET EASIER as each child gets more independant. I have two--8 and 5--and this year when my daughter started all day Kindergarten, it was a breath of fresh air and the very first time in 8 years that I had any sort of independence. My husband and I have always worked opposite shifts, but make an absolute effort to always make time for US, even if it's the middle of the night or 9 in the morning. I always give him a couple of hours a week to to his own thing and vice versa. I am pregnant w/ our third, so I know the days will soon be overflowing again. Sometimes when we do the "pass off" for days in a row, I feel like a single mom, but I remind myself that he is going through the same thing. I carry the family benifits and I also can not afford to quit or change my job. Just keeeeeeeeeeeep telling yourself that you are doing this for them! And my God, DONT feel guilty about staying in bed during your alone time or even slacking on housework. Just because you are a mom doesnt mean you arent human!
As long as you have a solid marriage and happy kids...you WILL get through this stage, and youll be proud of your hard work.
OR...get a nanny (dont we wish)!
