Ds is 4 and still rear facing in her car seat. She weighs just over 21 kilos and is really tall but still fits in the seat.
The problem we have is that she is begging not to use it, complains that it's not comfy and wants to face forwards like her friends. So far we just laugh and cajole her into it and she's ok once strapped in etc.
She starts school soon and keeps talking about being a 'big girl' who needs a seat like ds (who is 9!). She also says it is too hot as the air con doesn't reach her as she faces the wrong way 
When do most ERF users change to forward facing? And any ideas on how to make her happier in the seat?!
