You do not need a jogging stroller to go walking or jogging with your baby, however it is recommended, especially if you're going to be using your stroller to walk or jog on a regular basis, I'd say 3 or 4 times a week, if that's going to be your mode of exercise with your child. First of all, it's going to be more comfortable for you. A lot of times, the 4-wheeled or umbrella strollers are not really recommended at all. You're a lot lower to the ground. You're not comfortable. What you want to make sure is that you have good posture while you're walking. Make sure that your hands are high enough on a bar. So jogging strollers have straight bars. A lot of the times 4-wheel strollers have 2 handles. So you're just not as comfortable. They don't go over bumps as well. So the seam of walking over a sidewalk or asphalt is going to be more comfortable with the jogging stroller. I know when I went from my 4-wheel to my 3-wheel stroller was amazing. I couldn't believe I had walked 6 months with my 4-wheeled stroller. So going to my 3-wheel was amazing. And I was able to walk and jog with ease. And my child was a lot more comfortable and was happier to sit for a longer period of time.
