Hoping for suggestions for my boisterous and Houdini-like second son, 3 years old, who is 99th centile for height and 18kg. He is currently ERF but has outgrown the seat.
The mismatch between his height, weight and age seems to be giving me problems. Most of the seats I can find for his size are basically high back boosters for the usual seatbelt. He absolutely will not keep a normal seatbelt on -he escapes a 5 point harness without extra straps across the chest.
Our hand me downs for big brother don't work as big bro is 50th centile and managed ERF till 4 years old, so was mature enough for a standard high back booster at the point of going forward facing.
Have had a chat in mothercare and Halfords and staff were unable to help!
