Give her time, many changes going on around the kitty.
You moved and had a baby. That's allot for kitty to absorb in short period of time even tho it's been since June, kittys cant tell time or know a calender. To them it just happened yesterday. Give her extra scratches and belly rubs. Take time out in your busy day even if its for a few mins to play with her. More than likely she is feeling left out.
