So my 3 year old's pre-school sent a letter home asking us to practise counting forwards and backwards, and rhyming words together. "This looks easy", I think, and proceed to do some rhyming with the boy.
Me: "What rhymes with 'frog'?"
Me: "What SOUNDS like 'frog'?"
Me: "!!!!" (thinking, well I can't argue with that, he is right really)
