So we bought DS an ERF seat for our car and DS was ok to continue using his baby seat in GPs car but has now outgrown it and needs a seat they can use maybe once a week when they babysit. I'd prefer them to have a RF one but obviously can't force them to fork out as much as we did for ours and it probably needs to be easy enough for them to put in and out of the car.
Can anyone help me with a recommendation?
