nope, life form dont care about opinion of their children

They need only increase the hotness of the sexual forge to create a child with superior tensile strength

no because the entire point is to ensure the 1st child won't be spoiled.

LMAO. Why would someone that doesn't run nothing but his gameboy , when his parents allow him to even do that, have the say?

Yes, in fact, parents must get full written consent from their firstborn, have it notarized, and pay a processing fee before they can even start trying to have a second child. Breach of said contract is punishable by fines and prison time.

Everyone knows this.

This must be the most american thing I have read for some time. Along with a child suing their parents for being born. Stupid as stupid can get.

yes

not everyone wants siblings. next question

lmfao no

Only in China and only during their One Child Policy.

Legally? No.

If the parents are wondering this, then maybe they shouldn't have any kids at all

well no, but if the first child is old enough it would be a kind thing to do to explain the situation to them. you see this in films and such the parents ask their children: "would you like a brother or sister?" most parents do this to prepare their child, i think, so they do not fear they are being replaced or overshadow, so to speak.
