I gained a total of just over 13 kilos in my pregnancy. By the time I came home from hospital, 5 days after having DS, I had lost 7.5 kilos, by the time he was two weeks old I had lost another 2 kilos and I was back down to my pre-pregnancy weight by the time he was 5 monts old. He is 13 months now - still breastfeeding and I'm now 4 kilos below my pre-pregnancy weight!
