Do you have working mother guilt often or do you give yourself a break?

Even while working at home I'm feeling guilty about not getting enough done. I want to spend time with my son, but I also need to get some work done to pay the bills. But the housework is waiting, too. And my poor husband patiently waits for a bit of attention, too. I don't know how to balance it all where everyone's happy.

I felt more guilty when they were infants.
I went back to work when they each were 4 months.
Then worked 4 days a week for the first year.
Now that they are about 3 & 5, I can see how wonderful they are and how much they love me, and I dont feel guilty.
Only when I need to work late and cant tuck them in.
That is a big guilt trip.
Not singing them to sleep or reading books each night.
Only happens once in a while.
I do feel like the other post.
That no matter what i do it is never enough or should be better.
Its very tough after working, then spending precious hours with the kids, to then do chores around the house. Hubby and I eat around 9p each night.
exausting.
I have not been in touch with my friends because of lack of time.
And Lylah-
Yes, seems eveyone IS managing just fine, but they are NOT.
things arent always what they seem.
dont be to hard on yourself.

I feel it nearly every single night. Not about what I AM doing, but about what I'm not doing. I'm not on top of the laundry or the cleaning. I should be cooking more the night before. I should be organizing our bills and paperwork instead of stacking them in heaps on my desk and around my file cabinets. I should be better at everything. I'm doing the best that I can, but some days it doesn't seem good enough -- for me. Everyone else seems to think I'm managing just fine!
