Definitely not just you Dowski,

         If its not eating food leftover from when your baby/toddler is finished dinner, or just the fact that you're the one who does the shopping. So much of home-life revolves around food/food prep/food purchasing that its almost inevitable that some weight stuff is going to pop up. You just gotta paddle against the current. Not a good or bad thing, really. Just a thing.

       I had my weight issues before becoming a homedaddy though. But since then, I've lost well over 100lbs. (Weight Watchers, Exercise, Lifestyle changes, etc.)

You are not the only one.  I have recently started down that path.  So far I have lost about 30 lbs.

The first thing I did was start keeping a log of everything I ate.  I did that for a couple of weeks just to see what I was eating.  There are some web sites like daily burn that you can use.  Then I tried to fiquire out what a good caloric intake for me would be.  I settled on trying to eat 2000 calories a day.

After that I joined a gym.  I was working out 5 days a week.  Right now I am trying to make sure I go at least 3 days a week.  It usually takes me 2 hours, about an hour for lifting and an hour of cardio.  The gym has a daycare on sight, so the youngest goes with me.  If it was easier to pack him up and go I would still go 5 days a week.

Good luck with whatever you do.
