Getting back to pre-pregnancy form

I know it's early but I said I was going to be honest about postpartum recovery and it starts now.  Here are the reminder photos for you:

First postpartum shot taken 2 days after Liam's birth: (that little line down my belly is from the lovely postpartum undies not a linea nigra)

I gained a total of 22 pounds during the pregnancy and my goal is to get back to 140 pounds by 3 months postpartum. I have started doing NOTHING yet. I want to give my body at least 2 weeks to recover before I start going on walks or doing anything.  I weighed myself today and I'm at 152 pounds which is down 10 pounds from my final pregnancy weight of 162, that's just from the birth itself!
