Losing weight too fast?

Starlita

I’m a first time mom and currently breastfeeding my twins. I was 327 before delivering on October 1st. Flash forward to now, I’m currently 259 😅 my doctor said not to worry but it seems very extreme and almost impossible to lose 68 pounds in two and a half weeks. I eat about 4-5 meals with snacks in between (pretty much eating after every feeding) and I’m eating healthy food too like oatmeal, smoothies, and lots of yummy vegetarian meals so idk 🤷🏽‍♀️
