Size of weighted blanket for 10 yr old

[purplepandas]

I am looking to get one of these for my 10 yr old who struggles with sleep and wondered if anyone had any recommendation re size. Weight size I know as 10% of her weight (so 3kg one) but she is rather long! They are not cheap so keen to get this right.

Any good reccs for children's ones? Was looking at the Senso-Rex ones.

anyone?

Measure the child? Sorry not much help but hopefully bump for you

We bought a weighted blanket from John Lewis for our v tall DD(10) - they gave weight parameters and size. She has the 2.5 one - I have the 7

You shouldn't sleep with a weighted blanket on. A compression blanket is a better option.
