I had exactly the same problem but my older one was 7 months old when i brought a second puppy home. My first one had the same behavior as yours. All the time seeking for my attention and that was my hint that she would welcome company. I had no aggression problems. They are both female.
About potty training. The first two weeks my older one peed any were else but her pee pad but after that she trained the younger one better than I did. My vet told me that it would take a couple of weeks of this behavior because she will have to show the puppy that she is in charge. Now after one and a half year I'm grateful that I made that choice and I know that both my girls are happy.
