A tiny call-and-response rhyme that doubles as a swimming game, sending the swan out to sea and cheering it back. Easy to act out with paddling arms and gliding hands.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Swan, swan, over the sea;
Swim, swan, swim!
Swan, swan, back again;
Well swum, swan!
About this rhyme
A short call and answer for miming a swim: arms sweep out on swim, swan, swim, and back in on the return. There's no story here, just movement and rhythm, so it suits a wriggly child better than a sleepy one, especially paired with real arm strokes.
