|You simply can't get by without a car seat.|
But we do have a car seat that I bought new. While I do babywear, DP doesn't so much and we do use a stroller for outings to the park. My dad bought us the stroller. DP's mom bought us a bouncy seat and our son likes it so we do use it. It's a good way for him to get his arm and leg flailing exercise without knocking the wind out of mommy and daddy (he's a strong kid ... who'd have thunkit?) We have BPA free bottles but they never get used, and we don't own a crib.
