You’ve also ruled out TH by knowing one is heads. So the only possibilities are HT and HH. Is that not 50/50?

At least one is heads, but unless you know which one it is, you haven't ruled out HT or TH

But you do know which one it is, because you said "other child". As soon as you ask the question, you assign a specific outcome to a specific child eliminating HH and HT (or in the new example, BB and BG). "What are the odds they have a female child" and "what are the odds the other child is female" are not the same question.

it depends on how you know this information. did you look at one of the coins? then it's 50/50. did you ask a friend to look and yell you whether at least one of them is heads? then it's 2/3.
