Thin moms are the best moms.  I have nothing but respect for moms who stay active and keep their kids active.  Two examples, a very pregnant lady going backpacking while carrying a kid on her back while hubby carried the gear.  And, a couple moms running around a park with strollers, stopping by the water fountains to bring the kids out and holding them while doing squats/lunges and such. *edit.  The moms I respect the least are the lazy/fat fucks who just sit and yell, like the kid is going to listen.
