Working full time from home, means working all day. I am concerned he does not understand your home is like an office.
What exactly are you expecting your children to do while you are working all day?
If you were in an office and had the kids every day all day long, how would that work?
Make out a realistic schedule of the week day. Include the care of the children, breakfast, get them dressed outside play then , inside for quiet play 1 hour work, laundry, lunch for kids nap, work during nap, clean 1 bathroom, kids up, snack, play outside, come inside kids watch video, another hour of work, start dinner..
Are you seeing, there really is not enough time in the day for you to care for your children, take total care of the house and work full time around this.
What has got to give? Your husband needs to give a lot more help.
He is a member of this family and household..
He needs to stepup and take some of this burden from you. And the last thing he needs to do is to be on your back about a messy house..
He can come home and help clean and spend time with his children by bathing and putting them to bed...
