If a mum hates how her body looks after a pregnancy, would you advise her to go for liposuction?

Yes, but only if it's the last resort and if she can't seem to shake off the pregnancy weight via traditional methods. If it's in her budget and she really wants to do it, then I can't stop her but I will definitely try to steer her towards "natural" methods. I'm quite a work-out/exercise freak so I will definitely try to encourage her to try to lose weight via eating right and exercising. I have nothing against liposuction or plastic surgery but there are some risks to those procedures and if there are alternatives that are healthier and I can encourage her through, then I'd rather do that.
