LO is almost 14 months. Up to this point "tantrums" were mostly just a high pitched squeal and general arching away from something she didn't want to do. We ignored it and carried on about our business.
But lately if we don't let her have something or we have to take something away from her or tell her "no" (you get the picture...) she just breaks down and full on cries...the open mouthed wail that used to only be reserved for when she hurt herself falling over or similar. She does the wail with her eyes scrunched up, then after a few seconds, stops to peep and check we're still watching.
I used to think if there are tears then it's not a tantrum and they need comforting...but I guess I might be wrong reading through some past threads on here.
