Hi, yep terrible twos can start eary...dd1 started around 15 months as well. The tantrums, the screaming, the flop and drop, kicking, you name it. What I did notice though is that when she hit 2, she had a word explosion and was able to express herself a fair bit more and the tanties died down, then a month later she had another word explosion and less tanties. She is still a terror at times, but I am able to talk to her and reason with her to an extent. Shes 2 years and 4 months now. She still has the odd tantie, shes at times terrible to her sister, but its much better than when she was unable to express.

As for discipline...mmmm....just try whatever you think works. Time out, walk away from tantrums, talking. It is a hard age.

At 2 and a bit, I talk, I give consequences with reasons (not that she likes that and it makes things worse at times) i send her to her room and I take dollies away.

Good luck with it all
