Postpartum weight loss

I had our perfect baby girl, Eva Noel, on March 25th. I just had my 2 week follow up visit my midwife and I weighed in at 30 lbs. down from my last preggo weigh in?! I am breastfeeding, and my legs and feet were significantly swollen during pregnancy and they just really shrunk down within the last week. I am overweight, and gained about 60 lbs total during pregnancy. I just can't fathom a whole 30 lbs in 2 weeks... anyone have a similar experience or thoughts on this? Picture of me and my love!
