I got on here to vent about the same thing! I am feeling so tired lately, just worn out so that I actually laid down on the couch during dds nap and read a book! (haven't done that in about a year!) And am in the kitchen making dinner and notice my 4yo just throwing pieces of a puzzle all over the place! Urggghhh
I can really relate to a PPer about just relaxing and living with messy, but constantly keeping up so that it doesn't become chaos. That's where we normally fit, but it is so frustrating to be the only one doing it. OP you are so right, our husband's do work all day, but it's not like we don't! The kids are our double full time plus unpaid overtime job! --not like they are really a chore :( but it is darn near impossible to keep up with the house, laundry, dishes, meals, bills, yard, etc, plus be a healthy and happy momma, along with the work that goes into teaching, playing with and correcting our kids all day!
I know if my husband and I switched places he would be really shocked at what it takes to "just stay home with the kids"!
