Hello and welcome to YT! My two act almost the same way. If I'm showing attention to Gabby, Gage will jump on her to try to get to me, try to push her out of the way, something to get me to show him some attention. If I'm showing Gage the attention, Gabby will come up, bump my hand, bump my leg, nudge him out of the way, whatever it takes to get me to pay attention to her. It really is very sweet and cute how they both want the attention and neither wants to share "mommy"
