Have read conflicting advice about this, britax leaflet says they are the safest, due to better baby position, have read it reduces incidence of cot death and good for spine. Whichseems not to recommend them (but do not subscribe so can't read full reports) Any one know where to get impartial advice from?
The carrycot i am buying is the Jane one. i don't have to use it in the car as I have a car seat anyway but it would be nice to know which is better.
