DD is almost 14 months old and still fits in her Pebble. Her head is not above the top of the seat just yet. We don't have a car so she is in a car seat maybe once or twice a month. I'm not sure how much she weighs but at 12 months was 10.5kg and 76cm long. She doesn't seem to have grown much since then.
The Pebble says suitable for 0-12 months, up to 13kg or when the child's head has reached the top.
What do you think? Should she already be in a stage 2 seat? I know I need to get a new car seat soonish but is it dangerous to use this one for another month or so? All my friends out their babies in stage 2 well before 12 months, I don't really get it 
Also, I've seen the New Hauck car seat advertised that can be rear facing until 4yrs old. Is rear facing definitely the way forward or would forward facing be ok for occasional use as we are not likely to get our own car for a while?
TIA!
