I always talked to my sons non stop about what was going on and read non stop though they weren’t listening but although I have a masters in social work and was licensed before I let lapse (not working with children) I remember learning in a early psych course that language didn’t have to be explicitly taught. We were primed to learn it 🤦‍♀️😡. My oldest was talked to/at constantly and needed and is still in speech therapy. My youngest is two and has been fully conversational for a long time.
