I havent seen it, but I have to say Ive had 3 births, 1 forceps, ! c section and 1 natural on gas and air and the gas and air I would actually describe as easy!
I enjoyed it and was walking around after 15 mins

She should say her childbirth was easy not all births lol!
As for the skinny legs, I have the exact problem, since giving birth I have lost so much weight im 5 10 and weigh 115 pounds, I eat lots and take build up drinks. She may have a personal trainer etc but really she may not some women do lose like that!!
