Personally, I'm lighter than ever after having two kids but I know that's not the case for many. I've had long spells of being overweight but I've found that running after my children and cooking them good dinners have been good for my physical wellbeing.
A number of other ladies I know have ended up slimmer, maybe it's having less time to snack.
Before I had children I was so worried I'd never lose the baby weight as I felt I had heard so many stories of how hard it can be to shift, which I know is the case for some but I'm just curious to see if that's the norm or if most of us have found it's made us healthier and possibly lighter.
