I'm suggesting that you don't make up fictional dialogue.
I am not denying that kids are dying in this war. This has more to do with how Hamas are deliberately embedding themselves within civilians, preventing them from fleeing and using them as human shields than the IDF deciding to deliberately murder children. I am not aware of any other armed forces going even remotely to the same lengths to warn civilians as the IDF. They even invented the practice of roof-knocking, which Palestinians trust so much that they are standing within meters of a marked building in order to film its destruction.
Your second link does not support your claim that Israel said they are only killing Hamas.
