I have a car seat from mothercare, it is probably about 5 years old. I can't remember which stage is is, but it is one that can go rear-facing, then turn round for forward facing.
I know it can be fastened using a lap-belt, but cannot remember how! I did keep the instructions, but dh must have thrown them out. DOes anyone have instructions or know how it goes. We are planning a day out with my two and a friend and her toddler (she doesn't drive), and I'm not sure she would fit in the back!
