My ds2 (7 months) has just grown out of his stage 0 infant car seat. I have put him in dd's old combination car seat, rear-facing, because he is not old enough to go forward facing.
Now dd's seat is about 4/5 years old so obviously not ideal. Do I buy a combination seat so I can keep ds2 rear facing as long as possible, then turn the seat round. Or should I keep him in dd's old seat until he is 9 months (would like to keep him rear-facing a bit longer than that if poss) then buy a forward facing seat?
