14 month old possible speech delay?

Hello everyone!

I read that by 14 months your LO should be saying 3-5 words, and my son is only saying probably 2 words with intent. Which is “more” and sometimes “ball.” He babbles and will say “mama, dada” but I don’t think he’s saying it with intent. However, he understands more than he can say.

Should I be concerned? Or is this something that will progress over time? TIA!
