Christy, funny how people think all children's behaviour stems from how they are treated by their parents, as if!

...sounds like you are doing your best to cope with the tantrums; as long as you're stopping her hurting herself and you're keeping yourself sane you are doing a great job.

As you are pg, you couldn't try this, but could your DH try and hold her tightly to him when she starts a tanty, to stop her flinging herself around? It wouldn't be easy but it might offer her some comfort whilst she's having her tantrum. Just a thought
