You Know, I'm Just Like, Who's That?

I haven't always been like this, but I am like that now. You need to be careful if you get a spray tan when you're breastfeeding - it can leave the baby with a big face of brown from the spray tan. Is there anything you're absolutely hasing to get back into exercise? Would that be your number one thing that you've missed out on while pregnant? Or is there something else?
