I'm not even 150cm eek! Lucky I weigh more than 18kg so I don't need a harness
Is it ok to put something under a 4 year olds bottom to raise them up a tad in their seat? Thomas is over 18kg but the seatbelt guide on his chair makes the belt way too high. He's about 104cm.
I'm not sure but I'd fear something potentally sliding about under him could be unsafe. If finances allow I'd maybe try a different seat for him.
Is he tall for age? My boy is about 3 mths younger but just 92 cm.
I think he's on the 50th for height at the moment after a growth spurt but is usually 25th centile. Your son looks to be between the 0.4th and 3rd centiles?
I did buy a new seat which arrived this morning and is much better. It has lots of adjustable parts so the seatbelt will now sit properly. It also has isofix and a tether and some metal framework in the body so it's quite sturdy. I wish I could use the harness as it's so much safer. Stupid 18kg rule
. This one should do him until age 10/11 if he tollerates being in a seat for that long.
I bet the harness would work fine in a crash above 18kg so I wish they would test and approve them. Thomas still fits fine into the convertable seat he had as a newborn and I could still be using it instead of buying all these other seats, if they would test them above 18kg. He's 18.1kg.
As a side note, how do you stop head droop when they fall asleep? The big kid car seats are so upright!
