DD1 (4.5) is very proficient in throwing wobblies these days, but they are more of the Can't have/get what I want = throw a strop/slam doors variety. She never had tantrums as a toddler
DD2 (20m) OMG. Have noticed them over the last few days really... proper, full-on, screaming, foot-stamping, rolling around on the floor type. And they seem to be triggered by absolutely nothing of any real consequence (well to me, anyway!)
Happy Days ahead
Is it fairly usual for tantrumming to start about this age? Thought she was a bit young, tbh
