It's not easy Bella! My dd is 5 in March she is going to school next year but we only decided for sure two weeks ago, she wants to go and loves doing her words like her big sister and counting so academically she is ready but socially we were unsure but she is making big improvements to plays so much better with groups of kids and can deal with conflict without tears now so even her kinder teacher agreed she is ready. I think because she was so exposed to the school with her sister in prep she would have been mentally set back if she had to redo kinder. She has actually participated in a few classes when I have helped and she loved it. Good luck with what you decide.
