I am going to buy a new seat so that my new little mindee, who starts soon, can rear face until aged two. The parents request that it is an isofix but they are so expensive and a belt held one with good reviews will cost under £100. I don't earn a great deal and didn't earn enough to pay tax last year so I really can't afford the money or the space in my mpv for a large or expensive one. Any ideas, please?
