A cute way to help learn the alphabet is this 40cm circle wooden sign with 3mm acrylic raised lettering! 
Made in pastels with pink or blue or neutrals and 'I heart you' message or can be made with the letter I O U instead. 
Measures 40cm in diameter and 6mm thick.
Comes with a blank backing for you to attach what best suits your walls but is light enough to be attached with double sided tape or blu tac.
