My 3yr old is too big for his childseat (head coming over the top and can't fit in it if he's got his coat on!)
I was thinking of getting him a booster seat with a back on it if you know what I mean but he's only just 3 and not sure if he's too little.
Am going to weight and measure him tomorrow and see what the rules say but just wondered if anyone else has a 3yr old in a booster seat?
