Hi Folks. Travelling short haul with Mrs Roberino and Roberino Jnr in the near future. Jnr is 15 months so he is in a stage 2 car seat (6 months to 4 years). Ours requires an Isofix unit to fit it in the vehicle, so if we travelled with the seat we would need to take both the seat and the Isofix. Can anyone recommend a bag that will accommodate both these parts, please?
