How aggravating, when your baby's nap time is approaching and you need to make a journey out with them. For this purpose, it's worthwhile buying a pram with detachable carrycot or car seat. This is also known as a 'travel system'. When baby falls asleep in the car seat (some have an integrated swinging mechanism, which helps!), mum or dad can gently transfer the sleeping little bundle into the car. Once they've arrived at their destination, the car seat (including sleeping child) can be transferred onto the buggy frame, and the journey can continue on foot. The car seat is now securely attached to the frame - most of them face the parents. Some products are, however, more flexible. The bigger travel system you choose, the more use you will get out of it over time.
