Sounds like the 'terrible' two's and a bit of jealousy. My gf experiences the same with her DS and DD. DS takes toys off DD, pushes her over, sits on her etc.... all of which I am sure is a bit of jealousy and he wants attention. He gets the attention, but usually he gets sent to his room for time out. He seems to know what he is doing IYKWIM but he won't stop until gf & dh growl at him.
I don't have any advice on how to stop your DD, maybe more 1:1 time when bubs is asleep????
Good luck, hopefully it won't last much longer
