HI!! Glad you posted. Congrats on your new baby!
I know it's hard to look at a big number. It's has always been helpful to me to put my goals in five pound increment. (Read my saying below.)
I think the most important thing about losing weight is planning. PLan, plan and plan some more.
There are many plans to follow: Weight Watchers, calories and many more. Find one that suits you and tryit out and see how it feels.
Post often. Folks here are helpful and wise.
