What is an easiest way on how to teach numbers and letters to a 1 yr 8 months baby?

Sing him the alphabet mommy, count with him, kahit hindi pa siya magtalk the more na naririnig niya mas madali niyang ma adopt as far as i know. Pronounce clearly and make it fun. Ako ay bought noon mga visuals para may maituro turo siya habang binibigkas ko para sakanya. Repetition is the key. Goodluck mom!
