when i worked we were out of the house so no mess was created but now that me, ds1 (4) and ds2 (4 months) are at home there just always seems to be mess. i clear up and 5 minutes later more mess but baby needs fed/changed/settled or ds1 wants a drink/attention or the door goes or the phone rings or i need to go and get milk yadda yadda yadda.
Can you rotate what you clean during the week? Ie. Monday bathrooms, Tuesday living room, Wednesday hall etc. Rather than only feeling like you're cleaning if you're doing the whole house at once, which is exhausting. Or see how you find Flylady.
thursday is a day i dont have to leave the house except for school run so i try to keep it as free as possible so i can be really lazy all day if i want or i can take ds' out for the day if i want. and i like to keep the weekend as a weekend.
