Body after pregnancy

It's kinda sad to see so many girls on my fb atleast complain about being pregnant because their body will never be the same after pregnancy. Now is it just me or does that come off kinda lazy and immature. If you want a healthy toned body how hard is it to work out after you have the baby an get back into shape. A child and pregnancy should not be an excuse to stay healthy an fit. And to blame pregnancy for how your body looks is a little immature to me. If you don't want to lose your perfect body or work to get it back then why get pregnant? I'm due next month an I have every intention of getting back in shape and looking great this summer. Okay it might be hard but it's so worth the satisfaction of looking an feeling great.
