For DD1 please, shes struggling with carpet time at school atm, in the past she used to have one at school before, and her current teacher has asked me to get one for them to try.
It needs to be strong obviously and nothing that going to distract the other kids (ie no lights ect).
Ive had a bit of a google, but all the ones i seem to have found have either flashy lights, dont look very strong or cost the earth!!
