Talking

Just keep reading and talking to them. Theyll get it. Also dont panic over it. My eldest is 3 and half and is partly non verbal. My 2 year old copies him

No need to worry, hes still a bubba. Just talk about everything you are doing, what you can see on walks, point and name things.

My son started speech therapy when he was 2, so if his speech doesn’t improve over the next year, I’d definitely look into it. From what I’ve read, around 14 months babies are usually saying or repeating 1–3 simple words like “mama,” “dada,” or “baba”—nothing too advanced. At his well visits, the pediatrician should also be asking how many words he’s saying and keeping an eye on his speech milestones.
If he does end up falling behind, I highly recommend speech therapy. Around 21 months, my son started getting frustrated because he couldn’t communicate what he wanted. He would even hit other kids at daycare because he couldn’t find the words to express himself.

Reading and just talking. When you’re doing something say what you are doing. “Mommy is making ____” also, whenever he does say something repeat it back to him. Label everything, repetition is so important for their little minds! My son is 21 months and just in the last like 3-4 weeks his vocabulary has went from very limited to none stop talking that makes sense!
