Distal and proximal pointing

[Needer8954]

My son is 20m old. At 19m (1m delay) he started pointing outside at everything, people, animals, things, airplanes, birds and always looks at us to see if we see it too, but he doesn't point when asked or when he wants something (he has most things around him). If he really can't reach something he starts to whine to get our attention and starts gesturing with his hands "put it down" (he's been doing this since about 15m). He doesn't speak yet, only 2 words ba-ba (grandma) and da-da (father) and a few animal noises (but he's babbling different syllables almost all the time). He has limited time in front of the TV, but he does point to things on TV (and looks at us with a smile) or points to youtube to switch commercials (that's about the only request he asks us to do with pointing). Sometimes he points to dad and says da-da. Is it normal that he points outside almost all the time but doesn't point when asked or that he needs something?

It's a bit unusual, but that doesn't necessarily mean it's a problem.

With the 'put it down' gesture, does that include a way to indicate what it is he wants? If, say, you held up two snacks and asked which one he wanted, could he use his gesture to tell you which one? If so, he might not point to request because he already has a gesture that does that job.

With the pointing when asked, how confident are you that he understands what you're asking? Is it a case of if you say 'go get teddy' he does it, but 'point to teddy', and he doesn't? How is his understanding of what you say in general? Would he understand things like 'get your shoes', 'let's have a snack', 'time for a bath', and similar things around his everyday routine?

He first trying to reach item and then do the gesture. He rarely points what he wants, for example he was thirsty outside and I holding him and he start whining and pointing to his drink or kid was walking with the balloon and he started pointing to the balloon but I don't know if he just wanted to show me or if he wanted it.

He is not understand "point to teddy" his understanding was limited month ago like (give it to me and come) but after he started pointing he understand more. He now understand dinner time, bath time, get your shoes, throw it in the trash etc. (a month ago, he would only come if I turn on the shower). But he doesnt understand commands like go to the bedroom and bring 'x'. He can even make an animal sound when I ask him (only verbal, no picture) but hit or miss because sometimes he start whining, like I do not want to do it (its so common these days)
