Best DSLR + lens combo for low light, indoor kid shots

You But I thought you didn't own or use a DSLR and flash yet... how can you be 'well aware' of something you haven't used? Confusing...

You are on here asking basic question as if you don't know anything - but you do?

Like the situations you have been mentioning.

Hahaha... totally funny, and totally false! You paint the use of flash as some sort of negative or as a crutch that a 'skilled photographer' wouldn't - or shouldn't - use. You are far, far off the mark.

Flash can be used in all situations - low light, no light, bright light, indoors, outdoors... it's just a tool and the 'skilled photographer' will use whatever tools to get whatever look they are trying to create.

Right, well... go get a DSLR first, then try it, then report back with your successes... You may find that flash isn't the crutch you make it out to be. It's ok, a lot of beginners read the online mantra of not using flash and believe it - they just don't know that this advice usually comes from some self proclaimed 'expert' with poor or no knowledge of flash use.
