Hi there! Welcome to FitDay...you are in the right place to figure out how to do it the "right way." Most of our members are grinding through it the old fashioned way...focusing on nutrition and exercise. There are a few threads mentioning supplements, but I think we have a very wise community here with a lot of knowledge about what works and what doesn't. There really is no magic pill.
Have a look around the forums and feel free to jump in anywhere you like. There are a lot of moms with little ones and others of us with older kids who have been there, done, that, and can still offer sympathy and a smile.

Just remember, you will find what works best for you over time. Start by logging and looking at the calories compared to activity, then tweak it depending on trial and error. And ask for help if you need it!
You may want to take a peek down at the 7-Day Motivational thread in the Women's Corner...good group, lots of support, always good to share struggles and successes in!
