Teaching the alphabets at what age?

Hi Samantha different parents do it at different times, but i started playing with them with the alphabet even before they were a year old. by 1 year my babies could point out a lot of letters when asked. i didn't sit down with them with a list of the letters though, definitely not in an A to Z format. instead, i would point it out and say it out loud as and what letter i saw. gradually it became more of a play thing for them
