I think why a lot of people opt for the capsule for the first 4-6 months is the ease of transporting baby in and out of the car....without waking. Ive had a capsule with all 4 of mine...its handy when going to friends homne and baby sleeps, handy when ducking into the shops and baby is asleep, handy when baby is asleep after you get home, and you dont have to wake, to get out of the car....
