mother of 3, new to MFP, need to shed weight

hey guys and gals.
im 28 from southern california.
i am a mother of a 6 year old and 2 year old twins.

i have a sit down job and a hard time trying to shed this baby weight.

its hard cooking for everyone at home and not eat what they are eating. and working 6 days a week doesnt leave much time for exercise unless its late at night.

i just bought the jillian michaels dvd at walmart, i just need to find the time to squeeze it in my schedule. ive tried insanity and almost killed myself on the first day. i also have billy blanks bootcamp (just recently bought).

there is no time or money for a gym membership so im just looking to do this on my own at home. any advice????

i have 20 lbs to lose to get back to pre pregnancy weight...
