DD is only 14 months old but she has already started throwing tantrums mainly if she can't walk where she wants to go, pick up what she wants to pick up, etc. She has a very high pitched, piercing voice and literally takes a huge breath and screeches (don't want to make her sound awful, she is also a lovely, happy baby, but the tantrums are a bit of a shock for me, PFB that she is and all). I really can't over-emphasize how high-pitched the screams are though!
As much as I can I let her have her own way and that's fine, but there are times when she has to do otherwise and then she throws herself on the floor and screeches. At home I leave her down for a few seconds and then ask her if she wants to get up at which point she is usually a lot better, but this tactic doesn't work well outside, e.g. middle of the road or at a restaurant!
Distraction doesn't work very well despite my best clownish attempts and she's too young to reason with or give rewards/remove rewards, so I am a bit at a loss.
Add to all this that we are in France where people openly comment on 'badly behaved' children, so that total strangers will turn around and say "Why is she like this? What is wrong with her? She must stop". I know I shouldn't be affected by this, but I am!!!! (btw I do not stick around when she is screeching in public, I scoop her up and we go away from everyone).
Final twist is that she already weighs 13 kilos and physically it's quite a struggle to carry her, especially when she is unco-operative.
Anyway, sorry for the huge post!
