My little girl is a few days old and has taken to her Tripp Trapp newborn seat very well! My concern is that I've heard rumblings in the past about limiting time in car seats and as the seat is a similar position I was wondering if there is a recommended limit for time spent in a newborn seat etc? She seems much happier slightly upright rather than flat in her Moses basket etc - as she's got a bit of wind being upright more seems to suit her!
