I love banquette seating! A great breakfast nook/family dining option that just looks good in any kitchen. Especially in its own little nook with lots of light, and lift-up seats to store kitchen/dining linens.
I wonder if you could read The Rainbow fish togehther and use it to talk about friendship and self esteem. Perhaps write or draw on the scales things that make us beautiful because we can share them (a smile, a hug, being helfpul etc) This would work really well as a celebration activity with a big fish (perhaps reflecting on what we want Messy Church to be like).
