I'm so sorry about Ellis's passing. It does sound like Penny is mourning his loss. The extra crying and wandering around is her feeling a bit out of sorts without him there. I agree that with her current age, and the fact that she is missing her best friend, that you should give her some undivided attention for her remaining days. Once she passes on, then you will have plenty of opportunity to take in one or even two new babies and pamper them for many years as you have with Ellis and Penny!
