Looking for a pram or buggy for your baby or toddler? You use a pram with a bassinet when your baby is just born until about 6 months old. As soon as your baby can sit independently, you can switch to a pram with seat or more compact buggy. Do you have several young children? Then choose a duo stroller (space for 1 baby and 1 toddler) or a twin stroller (for twins).
