My advice is to not forget yourself. To be good at your job, you need to feel good.
You need a quiet room to work, wait for them to nap, put them at the daycare.
It's not because you're working from home that you have to take care of all the chores of the house. Share them with your partner.
You need to work out or do an extra-activity like painting, then balance your day to have the time for it.
