Using photographs of familiar faces such as friends or family members start the game by saying I spy someone whose name begins with... and give the sound of the first letter, for example 'b' for Billy, 'n' for Nanny... who can it be?
Together can you think of something alliterative to call them like 'Brilliant Billy!' or 'Nice Nanny!'
Some sounds are harder than others to think of names for, but ‘silly’ names are fine for this too, just make them up and have some fun!
