HI L.,
You CAN do it again. If the idea of dieting is daunting or depressing STOP, BUT make sure you are getting plenty of the good stuff first. For example, every food choice you make ought to contain fiber. Eat MORE, more vegetables, whole fruit, not juice as it has all of the calories and sugar with few benefits. Drink your daily water like it is liquid youth extract, when you eat your grains make them whole grains, no white bread unless it is whole grain, but don't be fooled, some that say whole grain have whole grain in them, but are not primarily whole grain. Choose Quinoa pasta, as it has a lower glycemic index, but tastes like the real McCoy (you know that bad stuff we grew up on).
Getting started is the hardest part, but you wll quickly see the benefits of exercising such as increased energy (and who can't use that with a new baby) endorphin release, and great mood elevating natural hormone relase too.
And above all, if you don't take any other advice AVOID ANYTHING with Partially Hydrogenated Oil. It is known to not only make people obese, but it is slowly killing people as our bodies have not adapted to metabolize it.
You can make these health changes fun, find new things, shop in the outside isles of the store first, these are your healthier products. You will feel good about setting a great example for your kids and helping them avoid the problems associated with childhood obesity. Childhood obesity is the number one marker for adult obesity. Above all, make exercise part of daily life, go out as a family and play, ride bikes, play ball, go on walks, so much in life to do that is active.
As for your milk supply, I can say with some authority that you can exercise and maintain your milk supply by drinking enough. If nothing else drink at least 16oz after heavy exercise. I always tell my clients, that with each time they nurse they should have a drink at hand and utilize it.
You CAN do it, your kids will be healthier for it, and you will feel SO much better. Have your snacks that are bad for you, BUT have an 8oz drink first, and eat high fiber lower calorie foods as a "go to". Use self control and rather than a BIG candy bar, have a regular sized and relish the taste, really enjoy it, and make treats just that TREATS, not part of your regular diet.
Please let us know how you are doing!
Best wishes,
