Every dead child in Gaza is to be attributed not to IDF but to hamas, as they are without exception victims of their human shield tactics. Hamas fires from school yards, hospitals and their leaders and command centers are intertwined with the living places. This answers your question.
Have you seen a picture of Gaza and how is it now? Schools, hospitals, mosques, churches, everything is destroyed. You cannot blame Hamas for having 40 thousand deaths if Israel is bombing indiscriminately all the land, including UN members, journalists and int. ONGs. Hamas were not using then.
No - the IDF are responsible for each individual kill, and more so if they are babies, kids and women. They are genocidal war criminals and you are a little irrelevant genocide cheerleader.
