I'm so sorry gorgeous ladies but I have no tips at all. The last week or so Olivia has been getting really aggressive with me. She hits, kicks, throws things, bites and screams at me. I tell her not to do whatever one she is doing at the time and if she does it three times in a row she gets time out. On the second time she gets told if she does it again she will get time out. I sit her in time out for 1 minute and then talk to her about what she did and tell her she has to say sorry (even though she can't talk yet) and we have a cuddle. And OMG Olivia does the laugh at you and comes right back for more.
I'll be using the same technique when bubba comes again and is getting some of Livvy's special attention.

Sending you a massive Lulu and Tan. Sorry I couldn't give you a magic fix. Hope things improve for you really quickly.
