Like a previous answerer said, take her on walks, & drink lots of water. Try to eat small, frequent meals, instead of 2-3 large ones day. It will speed up your metabolism. Substitute your bread, pasta, & rice for whole grain versions. Choose fat free milk, & try to keep your meals/snacks under 15 grams of fat apiece.

Look into a mommy and me exercise class or video. It’s play for them and exercise for you, essentially using your baby as a weight.

Start taking her on walks. This will be good for her to be out and she might even take a nap in the stroller, and it is great exercises for you. I know that last thing you want to do when you have a newborn but you could wake up in the morning a little earlier then she does and just do some workouts at home. Remember to start out slow, it took nine month to put the weight on. Congrats on losing 30 so far, that is great in 3 months.
