I attend a free baby singing group at the library every week.
I am by no means fluent but as my eldest is non-verbal I can do a a decent amount of basic signing, including nursery rhymes.
So naturally I sign to my youngest too.
The other mums obviously notice and the animals at Old McDonalds farm have been getting ever more exotic - last week I had a bloody Llama! (After Hippo, crocodile and elephant failed to stump me 😂)
And the leader has started introducing more rarely used/obscure songs.
They enjoy seeing my WTF face, don't they? 😂
