I've just bought this seat for my 14 month old, as he has outgrown his Maxi-Cosi, but I'm a bit concerned as it seems to have quite a bit of sideways "wobble" and he's started being car-sick, which never really was an issue before. It could be a coincidence, as he's had a bit of a cough which can cause him to be a bit sick, but I'd be interested to know if any other Mumsnetters have used this seat and had any similar problems. The seat is fixed onto the Isofix points and all the indicators suggest that it is correctly fitted.
On another point, his head seems to fall forward when he sleeps, is there anything we can do about that?
