Do you know how many kinds of baby stroller or baby buggys are there? Usually, baby strollers typically fit into one or more of these:
 
Umbrella
Lightweight/compact
Carriage
Jogger
Rugged/all-terrain
Full-size single
Travel system including an infant car seat

Make sure the category you choose fits your routine activities. You may find that your lifestyle requires more than one stroller to adequately meet your needs.
For example, while jogging strollers are great for outdoor activities and walking over rougher terrain, they may be cumbersome for trips to the mall. Lightweight strollers tend to be preferable for travel but don’t perform as well at the park or on a sandy beach.

Try out several strollers at the store before you make your purchase. Open and close them. Put weight in the seat and push them around the store. Check out the different features and adjustments, and test how they work.
