Hi. We are in the uk.
Dd is a giant. She is 2 1/2, but the size of an average 4 year old.
Weighed and measured yesterday. 99cm, 17.3 kilos.
She is currently in a britax 1-2-3, using the 5 point harness.
Very soon, I am guessing she will hit the magic 18 kilo cut off for the buckle.
I know the 1-2-3 converts to a high-back booster, but without the harness, every journey will take a million times longer while I put her back in the seat every 10 feet.
She has no concept of "sit still, even though you know you can escape"
We are going through diagnostics for several things including co-ordination delay.
I don't have masses of spare cash to buy lots of seats, especially as this one is a decent one and I would like it to last.
Is there anything I can do? Apart from gaffer-tape her in?
Never drive again?
It has crossed my mind to try and find out if it is safe to use the 1-2-3 in both modes, together.
Put the adult belt around dd and the seat, as for a child over 15 kilos. Which she is.
But keep the harness on, to keep her in! Then the buckle wouldn't be under strain, as the "safety" is coming from the adult belt.
Is this possible? Safe? Logical?
Who could give me a "legal" answer? Britax? Mothercare? Boots?
