Toddler talking

Mckenzie

My son is 20 months old and he still doesn’t say any words except for dada. He doesn’t even like to try repeating anything we say. It’s strange because he babbles and makes noises all the time. He’s really good at making car and truck noises. I know he understands the words like when we tell him to touch his head or his nose, he’ll do it. Idk if this is normal for him to be this old and not talk yet? Anybody experience this?
