The letter U is signed by holding up your dominant hand in a fist, facing outward, with the index & middle fingers sticking up while held together.
Teach your toddler the letter U sign when it is necessary to finger-spell some simple words - or the initials of objects, places, animals, or people's names. That way, your toddler slowly begins to associate the sign with the sound of the letter in a word or name.
This is a useful flash card taught best in conjunction with the other letters of the alphabet.
