All you need is a cup of water and a brush. Today your little one paints letters on a fence, wall or path with plain water, then watches them slowly disappear as they dry. It's magic, it's mess-free, and they'll want to do it again and again.

The book takes each sense in turn: sight, hearing, smell, taste and touch. For each one, it pairs clear photos of everyday things with simple words that describe them, like cold, crunchy, colorful, soft and loud. It encourages kids to notice what's around them and find the words to talk about it.

Today we're learning D. For toddlers the goal isn't writing it. It's hearing the /d/ sound at the start of words like dog, duck and dad, and connecting it to the shape of D: a straight line and a big curve.

It's Letter D day, so snack time is all about the /d/ sound, like dip. Your little one hears the sound again and again, dunks, dips and crunches, and builds a big D out of snacks before eating it.
