Welcome to YT, Give your lil boy time to adjust to a wee lil hyper baby. My first pup was 3 y/o when I got my 2nd one. Because puppies like to jump and nip at tails & ears and their baby teeth are very sharp, my older girl took to high grounds, the sofa, as soon as the pup got big enough to jump on the sofa (it took her about 2 months to learn to jump up onto the sofa) there was no getting away from the baby, also by this time my older one was use to yappy jaws, and knew she was there to stay. When that pup was 3 y/o and the other was 6 y/o I got my 3rd baby, again the 2 older ones hit the high grounds, again the sofa, again, 2 months later the baby was able to get on the sofa. They all got along fine, slept together in one puppy bed even tho they each had their own bed, they would all snuggle together. You must remember your lil boy was the only one, now you have bought another into his home. Babies need a lot of attention, just make sure he gets more attention then he did when he was the only one. He will adjust. Good luck
