A cocoon or babynest is an alternative for a carrycot
A cocoon replaces a carrycot, you just put the cocoon on the seat of the stroller or buggy. Most cocoons have flexible sides and are therefore easy to fold down.
You need a stroller or buggy that has the full recline backrest, otherwise your baby doesnt lay in a horizontal position.
Before you decide which cocoon to take, make sure the seat of your stroller is wide enough for that cocoon.
