New to the site...not the process

Hi, I'm new to the myfitnesspal site. I'm an almost 40 yr old mother of 4 boys, ages 17 to 1....I know! I found the app last night on my iPhone and love it so far. I've struggle with making wise choices and sticking to a fitness routine. I've done well in the past but an unexpected pregnancy and life struggles have sidetracked my progress. I was excited to find this site especially yesterday because it was one of those days where you tell yourself...enough is enough! So here I go, determined to stay on track and follow through everyday! I've used other sites and have had success with SparkPeople. But this site and app look even easier to use.
