This sounds like a great first day of school - I am so glad for you and your dc!
The ladies are right - housework will always be there. I know how it can weigh on a mama though, especially when expecting and unable to do things normally done. This too shall pass!
Some things just do have to be let go sometimes. When I am feeling weighed down by household tasks, I like to think what is REALLY bugging me the most. Usually there are some things that I can let go, and others that are truly driving me nuts.
It's the 'driving me nuts things' I do or have the kiddos do as soon as possible. I bet you know one thing that is driving you nuts right now, and if you have one of your dc do that 1 thing (and maybe they get a little reward for doing it - i.e. hot cocoa, extra computer time, later bedtime, a dollar, or just a very happy mama
etc.), then you can move on to the #2 thing that is most unnerving the next day.
Works for us! However, bedrest during pregnancy did help me become more able to let some things go. So be sure to give yourself some well deserved grace at this stage!
Your most important job right now is safe-guarding your health and baby's health. Anything standing in the way of that will just have to wait its turn for your time and energy - and that's just fine. Praying for you, baby, and family, but CONGRATS on a great first day!
In Christ,
Julie
My daughters were up before me, getting their day started. By the time I got out of bed, dd 12 was hard at work on her Independent boxes in CTC and dd 14 was ready to go with dh to get her braces off
