Lending Baby my hat

Playgroup in the morning with S, I, T, A, D. Afterwards we were not allowed to go to the playpark. I wasn't happy, but inadvertently fell asleep.
Later we went to the playpark and Baby refused to wear his hat so I lent him mine - well, I do have my helmet on all the time. We met F and his sister S at the playpark. We played with my ball.
