Unbearable Weight

I'm gaining weight everyday! I thought I was safe because I'm still breastfeeding but apparently, not. For the last two months, I gained a total of 6 lbs, which normally shouldn't be a big deal. Only it goes to my thighs and hips that I'm not comfortable wearing shorts anymore. Summer is here and there's no time to lose. I need to take out our rusty fitness equipment from the stock room so I can get back into shape. The problem is will I ever find time to exercise?
