I'd prefer if it didn't have to go through this at all. Knowing you are headed for bad times isn't something to live with, it's something to fix. And it's not like the birth rates in each state are staying the same, they are actively dropping. The issue isn't just there, it's also getting worse.
Then don't raise them! Also, don't raise problems that are easily disproven with real numbers! Demographics is a terrible domain to vibe your way through.

I literally just showed you that demographic projections for India give realistic scenarios for the number of under-18 year olds being equal to the number of over-80 year olds by 2100. The worst case is a 5:1 ratio.
exactly. so in 2150, or 2200, or someday, it will be a problem. So yes, it is a problem even today. It's kind of why you don't stand on train tracks even if there are still 15 minutes.
Future problems need to be fixed, else you end up as the countries you listed, Korea and Germany. It's not that hard
No. Never of the magnitude you suggested. The population pyramid simply doesn’t have the shape required for a population bomb the likes of which we’re seeing in e.g. Korea.
Given current and projected fertility, it never blows out the way you suggest. It gently curves. If Indians, tomorrow, suddenly stop having kids that would be the problem you suggest. But they aren’t. And it isn’t.
Smooth population decline means much less contention on ressources, energy and living space, which is highly relevant when all of those are already somewhat at the limit.
Significant positive growth is clearly completely unsustainable even over centuries, and I don't see why a somewhat smaller total human population could not be just as successful/satisfied over the next decades.
