Safety

Double-running buggys come with three or four wheels, similar to a pram. However they tend to be larger and the front wheel is locked to provide additional control and suspension. The handlebars will typically have brakes (similar as bicycles) so you can stop your buggy swiftly, and most have a wrist strap for added safety. There are also some that have a slightly reclined seating to provide extra comfort when your children are taking a nap or eating. It is recommended to wait until your baby is at least nine-months-old before taking them out for a jog, and only when they are comfortable.
