Please help!
DD is a bright and happy child. She's 2 so I expected some tantrums but last night was beyond any expectations. 
When she doesn't get her own way, her beautiful face changes, she looks right at me and hits me. She always gets a firm telling off but we move on quickly and it gets forgotten...until the next time. Am usually able to distract her before a tantrum begins. Maybe in the car it is worse because I'm driving.
Last night she didn't want to go to sleep. She was overtired after a full week. But she screamed and cried for almost 2 hours. She's still in her cotbed- I had put the bars back on after advice on MN to help her feel secure at bed time. (Which worked btw) DH and I would go in periodically for cuddles etc. One time whilst I had her in a cuddle she got both her hands and hit me round both sides of my head 
I put her down, walked out of the room and tried not to cry myself and let Daddy try. We are at a loss. My nieces and nephews never did this. So both DSis' at a loss to advise.
I love her with all my heart. I feel like a crap mum.
