K.P.
I am a SAHM to a 19 month old busy little guy. My husband works outside the house, and I handle the paperwork for our business--paying bills, ordering, etc. Our day goes like this--wake up at 6:30, play with dad while mom makes breakfast and coffee. Send dad to work, watch cartoons for about 30-45 min while mom gets her game face on and figures out the day :) I cook every single day, we don't have help and on Mon and Tue, I watch a 3 month old boy for 8 hours a day. My son is very independent and is happy to play by himself while I get laundry started and lunch/dinner. Nap is at 12pm sharp, and for the hour beforehand, we eat lunch and read books. He naps for about 2 hours during which time I clean the kitchen, start dinner, dust and pick up the house. Once he is up, we do a chore together--whether it is vacuuming, folding laundry or emptying the garbage cans. Then dad comes home, play time, dinner, bath and asleep by 7:45pm. It is crucial for me to have a plan for the day, because otherwise I get too scatterbrained and my son can feel that and feeds off my energy and gets hyper, so to speak. On Wed, we have a playgroup, and on Thur, we have a music group for tots. I"m not saying that my house is clean, but I'd rather have a happy baby than a spotless house :)
