Temper tantrums

Hi Mum's

I'm a first time mum and hoping to get some advice regarding my 11 mo daughter who in the last couple of weeks has started throwing major temper tantrums.

Everything seems to be a fight and ends up with her screaming and throwing herself on the ground which has resulted in one worn out and grumpy mumma.

She has always been a great baby but is very clever and strong willed. I think she is too young to be having tantrums. What steps do I take to avoid the behaviour getting worse as she gets older? I try ignoring her or removing her from the situation but it doesn't work. Is this just a phase and she is testing the boundaries?
