Katek, I'm in the same position as you. Last week, My son and DIL suggested being in a bubble with me, to allow me to hug my DGD. She has not hugged anyone else apart from her parents during the whole of lockdown and as they were being very careful and self isolating, the risk is very low.
However, to our shock, last week my wee four year old DGD received ( a very late) shielding letter, which which meant that we could have all been shielding together from the beginning.
The risk with children under eleven is low and you yourself will know if your family have been adhering to guidelines, so you have to make your decision based on that.
Wishing you all the best and hoping we will eventually make it to another Edinburgh meet up.
