I shall be collecting my 1st car soon.
We already have car seats in dp's car which consist of a britax(renaissance?)which was dd1's which is now dd2's and dd2 is in a cheap booster seat.
I haven't much of a budget but can't be swapping the car seats over from car to car all the time.
dd1 is 6 and tall like 7-8 year old and weighs around 3 and a half stone ish.
dd2 is 2 next week ,tall like 3 year old and very heavy ,off the scale according to hv
can't remember exactly how much though.
Sorry am clueless as well as pennyless.
Also with regard to dd2 she will never keep her arms in the straps so permanently sits with arms out .We have tried everything but nothing stops her.
