So my 3yr 8 month old is approx 20kg, we've had him FF in his britax multi-tech III for a few months, and have just realised, I think anyway, that the 5 point harness is only safe up to 18kg.
But its not safe to have him FF using the car 3 point seatbelt till he's 4, If we've understood the guidance correctly.
Where does that leave us? Obvs we could go back to rear facing, but he's going to hate that, plus we've moved house and aren't sure where the tether straps are for the seat.
Any suggestions would be very much appreciated, thank you!!
