How Do I Tell a Parent Her Kid Is Out of Shape? [View All]

My girlfriend and I live in San Francisco with our three-year old son. If you live here or have ever been here, you know that the hilly terrain turns a simple stroll into a workout. When he turned two, I quit using our stroller because my son was getting too heavy to push uphill and I thought the exercise is good for him. However, we frequently babysit another boy about our son's age whose mom STILL pushes him everywhere. Last week, we walked with both kids two blocks DOWNHILL to a Walgreen's and by the time they got there, the kid had to lie down on the floor to catch his breath. Just a few days before that, he only managed to walk half a block before he started crying. My question whether we should tell the kid's mom that she needs to ditch the stroller most of the time or let her push him around so he can continue to walk around out of breath? What do you think?
