Hi...welcome to Yt and I'm so sorry you're dealing with a sick little one. The anemia could be responsible for your baby's lack of energy. Is the anemia a result of the parasites? Hopefully now that she has been treated for them and the URI she will get better. If she is eating a dry food somewhat, maybe you could find a kibble she likes better than the Royal Canin. There are better foods available, perhaps one she would like better, that would benefit her and allow her to gain some weight.
I found your other thread here:
