Quick short story, any feedback?

If this is about you, then don't seem like a very good sister to be honest... It's normal to get jealous when you have a new sibling but not to that extent, damn. And as far as breast feeding goes, a child is going to take whatever is offered especially at such a young age where they don't know better... Anyways, you do have a good writing ability just change the story up a bit.The whole 'breast feeding' thing was a bit much and sounded too melodramatic... change the tone up, it sounds way to dramatic and angry. You didn't even explain why the speaker had so much resentment towards the younger sibling. It just made you sound angry for no reason. From the story you depicted the younger sibling as clingy and annoying but at most the speaker expresses an annoyed tone but still a loving having some sympathy as well because after all it is their brother or sister. My little brother was way worse then this and I still don't have such hateful feelings towards him. Sometimes that's how younger siblings are: annoying and selfish at times. But that's normal, however what's not normal is the speaker and how sociopathic he or she sounds
