New Mom trying to lose some weight

Hi All,
I'm a new first time mom (my son was born May 17). I still have about 10 pounds to lose until I'm at my pre pregnancy weight and I'd really like to lose a bit extra on top of that.
I'm serious this time.... I've "tried" to lose weight before, but not really. Something inside me though has changed. I feel like this time I'm going to stick to it and get healthy and get to a comfortable goal weight!
So not sure how this part of it really works, but I hear we should make friends...so if anyone needs/wants a friend I'm here for you if you'll be here for me! :-)
Good luck to all!
