Getting fit for future families

Anyone else using this as their motivation? I have a little girl born in March 12 weeks early due to high blood pressure, pre-eclampsia and HELLP syndrome. My obstetrician has he wouldn't discourage us from having another one, but he or she is likely to be born as early or earlier than my little girl. If I loose 2stone he reckons I might get at least an extra month, which would take the baby out of the danger zone. He also recommended trying between 1 and 3 years after my little girl, as apparently that will buy me some more time too. So that's my plan, I started a few weeks ago, but had a weeks holiday with lots of eating out, a wedding, and a weekend of staying with my father in law so no control over food in the meantime. I would like to have all the weight gone by my birthday in Feb, but I'm calling my goal my little girl's first birthday in March, anything earlier is a bonus. I'm really determined to do this and would love anyone else motivated by their families (be that future baby, husband, wife, partner, children, parents anyone really) to join in for a natter and some morale boosting on the journey.
