Not a question but a recommendation. We bought and used a Trunki for our 4 year old. It was excellent! We have 3 kids, aged 6, 4 and 1. When we are flying as a family the 1 year old goes to the Gate in a stroller, the 6 year old walks, but depending on time/tiredness/distance the 4 year old needs coaxing or carrying or goes in the stroller whilst we carry the baby - but not anymore! Trunki is a ride-on abs case that looks funky and is great fun. Click on the link to see it as pictures describe it better than words. My 6 year old, 4 year old and 1 year old all wanted to go on it - but the 6 year old was too large and the 1 year old too small but it was ideal for the 4 year old. We have never had such easy journeys to Gates! Strongly recommended to all.
