My boy turned 1 year old recently. I play with him all day and he is on track in a lot of ways. He hasn't said a first word yet and is currently walking assisted. His doctor said he's too young to learn letters but all the toys that are 1+ have the alphabet. His attention span can be short with me. My mom (his granny) has better luck sometimes. What are some things I should implement learning wise in his daily schedule? What and how do you teach your 1 year old?
