@Alejandra thank you! He's very active and I see he understands the world around him to an extent, but he's just not doing some stuff I read he should be doing by this age. Mainly banging two objects together and clapping
Yes, it is unusual to not bang items together or clap by this age, but probably no biggie.
Should he learn it on his own, or by modeling?
Modeling is fine, I think they usually learn clapping on their own or from others, but banging toys must be organic because grownups don’t bang toys together.
That's making me extremely concerned. But thank you for your response anyway
Based on what he does I wouldn't be too worried. He probably knows how to do it but doesn't want to. Skills may take a while yo show up after a leap.
