When should they be able to sing ABCs?

Um, we are first time parents and kind of just realized no one has been singing the alphabet to her 🤦🏼‍♀️😂.

She can count to 20 and identify written numbers 1-10, but obviously since we only realized last week that maybe there were those pesky letters too, she only has a couple of groups of letters.

Whoops. She starts daycare in a few weeks, is our parenting going to be judged super hard 😅?
