How do you handle a toddler throwing temper in public? Do you yell at him? How do you handle this situation?

It depends on what your "parenting style" is, and how you choose to react. I'm thankful that my son is just cheeky, not entirely "naughty", so he seldom throw tantrums or "behaves badly" - there are times that he does get out of hand too, but he quickly "recovers" from it! I'd say that not many parents would agree/understand my way of parenting, but they are just a few years old so they don't really understand that much logic/concepts yet. The first thing I'd do is always try to speak nicely in a calm manner - one of the reasons parents quickly yell/scold/beat their child is because they feel "embarrassed" that their child is behaving like that in public. There's nothing wrong with tantrums because they're just trying to tell you something! I'll carry him/get down to his eye level and try to talk to him, and I'd just keep a calm but affirmative tone for him to calm down else I won't want to talk to him in that manner - and he'll stop. If he does respond, then ask what's wrong - if your child can't talk yet, all you could do is assume the situation. Acknowledge his feelings BEFORE you address the issue, even if you know he can't reply you - you have to keep calm and let him know that you are trying to understand him and solve problems together (not about the tantrum, but what caused the tantrum). I try to do gentle/peaceful parenting as much as possible, so I'm one of those mums who talk things through and may seem like a "helicopter mum" (or maybe I am haha). But when my son still doesn't calm down, I'd just give him a stern "please behave yourself", then carry him out of the place and I'd just keep quiet until he calms down before talking to him again. Whatever you do, whether you agree with me or not, please do NOT publicly scold/beat your child!
