Just from my friends, I can see that everyone is different, but for me, I have never felt back to normal.
However much weight I lose, I have stretch marks and lose skin on my stomach and my breasts aren't as perky as they once are. I lost a lot of hair in the months after giving birth (although I have really thick hair so this didn't bother me) and I also look tired a lot of the time!
However, I am now lighter than I was before either pregnancy, and I actually feel healthier, fitter and stronger, mainly because before I took it all for granted and now I have made a conscious effort to work at these things.
I would say for the first few weeks post partum, I didn't recognise my body at all and I basically didn't look in the mirror, wore a lot of leggings and baggy tops etc etc.
After about 6-8 weeks, I started to feel more ready to assess myself and think about what I wanted to change - so I saw a women's physio to check my back, my hips and my pelvic floor. I started seeing a PT who specialised in post partum women, and I started putting in a little more effort to my clothes, skin care etc. But all in all, I would with both of my kids, it took me nearly a year to feel like I actually owned and controlled my body again (and actually in hindsight both times that coincided with me stopping breastfeeding)
