Standard- size strollers usually are 3-wheelers of 4-wheelers, and these models normally come with all the accessories for everyday strolling. 3-wheelers are great for brisk walking or light jogging. Remember the bigger the wheel, the bigger the work-out potential. Tandem strollers are double/triple, not just for twins or triplets, these strollers often accommodate younger and older siblings. Light-weight strollers, also known as umbrella strollers, are the ultimate travelling companion. They are easy to fold and carry. Light-weight doesn't have to be light on features. Travel Systems is a trend for many strollers: this combo lets you attach the car seat to the stroller frame until baby can ride in the stroller. Carrier frames( basic frames that hold the infant car seat) are a great option too. Often car seat adaptors let you mix and match strollers and car seats from different brands
