We have a group 0 Britax car seat which is for a child up to 9kg. Our DD is nearly 16 months and not yet 8kg, but nearly average height.
As we do not have a car, we've used the group 0 seat maybe 3 times and thinking of passing it on to a friend who is about to give birth, but I hesitate if DD is too small to go into a group 1+ seat?
Any advice? At her centile rate she'll be 2yrs old before she reaches 9kg!
