I know that it is tough to raise kids, run carpool, cook, clean and stay looking fabulous, but you must. Organization and prioritizing for us moms is critical for our own insanity. I suggest that you break everything down by days. Get that calendar up to date, and there are great meal plans out there where you can prep your whole week in a day. The Fresh 20 is a great example of a budget meal plan for families that I use!
Also, you may want to look into sharing carpool and babysitting responsibilities with another neighborhood mom. Most importantly, you need to create a date night at least twice a month where your hair and makeup look great and you wear some sexy underwear. If the house is a little messy so be it, somethings got to give. You are not Wonder Woman after all.
