she has a had a really big change babe! Wanting your attention is not manipulating you its her way of getting emotional connection she may seem like a handfull but maybe she is a little jealous that you are spending more time with your DP? Its hard for a baby to understand why mummy is not there for just her anymore.

I think your DP is being a bit harsh personally, He has never had kids and as we know kids do things, they write on walls they scratch stuff alll to see what happens, I think he needs to be more comforting and spend more time with her if anything so she can see the move was a good thing and she wont be angry at your DP for "taking" you away?

She is probably too little to sit and talk her through it but everythime she lies explain that its not nice etc?

Good luck babe I know you will work it out xxx
