Can anyone recommend an affordable mainstream or special needs car seat for an older child? I've just been told that we will not get funding for a SN car seat with swivel base (essential if I am to maintain my back intact). I have looked at the Britax ones and they seem ok although one is double the price than the other and I don't know whether to go for the expensive one now or whether the cheaper one will do for the next few years (my son is a big 2 and a half). Any advice would be appreciated. Thanks.
