No I didn't.
Your second point literally makes no sense and is based on the straw man that babies are holding guns where I made no point even related to that or collateral kills (which are unacceptable). Secondarily my point is based on internationally legal definitions of combatant and evidenced with a video of combatants being trained. Not like the UN and UNICEF haven't been all over this for decades.
Don't use child soldiers and you won't get statistically significant child casualties.
