I used (and am still using) MFP to track everything. Its an awesome way to make sure you're getting everything you and baby need, plus a way to make sure you're staying hydrated. When I told people, I cannot even explain the "concerned" looks I got, like it was some sort of eating disorder!! Shit man, apparently other moms think you need 4k cal a day, and it offends them to even think that's not true. I'm 4 days postpartum, and I feel amazing. I'm already back to doing my normal things and I'm back to my normal BMI. I guess I'm just "lucky" though! Fuck that.
