19 mo having such major tantrums, she's making life a nightmare for me and 3yr old ds

[BurningBuntingFlipFlop]

I thought my ds had tantrums at this age, but clearly i hadn't seen anything yet!

She's throwing herself on the floor, writhing aroung screaming and shouting "NO" for about 40 mins at a time a few times a day. Any about of trying to cuddle, talk to, sing to etc just makes her look more like her head my explode!

This morning it was because i tried to feed her her porridge, then after breakfast she started again, i'm not 100% but think it was to do with whhich cup a gave her.

I've taken to just ignoring her but it's a bloody nightmare and i feel like i'm walking on egg shells around a ticking time bomb!

She, unlike my ds, was the happiest, most contented baby i've ever met. It was overnight at 18 months this started. She hasn't got many words so i completely understand she's frustrated but i feel so sorry for my ds because she ruins everything!

Any advice? Thanks!

Is she frustrated with not being able to feed herself? can you try a finger food breakfast to get something in her while you spoon stuff in? She might be hungry hence later tantrums.

Can you try sign language - or having basic made up signs for things so she can try and tell you things?

DS gets stroppy when hungry, tired or ill. So I have a lot of snacks to hand. I also talk to him loads - instead of saying what do you want, I'll point to whatever it is I think and say "the cup?" to see if he wants it. We also do signing which he is starting to do back (he's 14 months).
