So I have bought a travel system which obviously comes with a car seat that clips on to the chassis and have also got the isofix that clips into the car. But I just feel like it's a bit flimsy and am considering buying this mini mouse rear facing proper seat in the george baby event that does from new born and up that Will stay permanently in car. Luckily I have a big boot so can pop the full pram in there. Which means the isofix can go into daddys car for the rare occasion he takes her out in it. What I want to know is
1- how long is a baby in the travel system car seat?
2- is buying another car seat a waste of money?
3- would a proper seat be safer or am I worrying for no reason?.
