I am looking for any helpful advice on apartment living with baby on *gulp* the third floor of an apartment. Specifically, i get nervous taking him up and down the stairs. They're located outside (like most apartments I know of), so they are frequently wet and are concrete not carpeted like would be inside. I typically buckle him into the carseat, but was thinking of using wrap or harness, in order to also carry stroller to then push him around the complex in. Any thoughts? Other options would be to store the stroller in the car, but then I risk it being broken into.
