I didn't buy a stroller until LO was 3 months old - all I used was the carrier. I bought a jogging stroller at 3 months since I am a runner, but it is very jogging-specific. I can't take it on public transit and I don't bring it in the car. I don't have anything else - not even an umbrella stroller! So I essentially only use the carries unless I am out running. A regular stroller would def. be a waste of money for me! I may get a cheapo umbrella stroller one day, but haven't needed one yet.
