Of course, both products have their advantages. Most families have both a stroller and a baby carrier at home. The most obvious reason to choose a baby carrier for outdoor activities is that it is nice to have your baby close to you when you are on the go. Or… because your little one clearly prefers it this way!
Another aspect that many parents appreciate about a baby carrier is how easy it is to use public transportation. Many parents get nervous at the thought of getting a stroller onto a train or subway. With your baby on your chest, you can easily get on and off and even use the escalator.
And when your child is old enough to ride in a bike seat, it's very handy to be able to bring a baby carrier along so you can easily continue on foot after your bike ride, for example when you go into a store.
