You could do a very weak camomile tea and tiny jam and cream cheese sandwiches. You could invite Great-Grandma to tea as well so she can see for herself how much your DD in enjoying the gift.
I would but she lives on the Sunshine Coast, which is about 1300ks away!
Love the ideas! Those tic toc biscuit things are so cute! We will take plenty of photos to send to nanny instead might wait for warmer weather so we can do it outside.
