Congrats on your new baby and just know that you are not alone. We had Georgie for 2 years and then our son came along. I am convinced Georgie thought at some point Isaiah would leave LOL. Anyways, a couple of suggestions we tried to pay as much attention to Georgie as possible when Isaiah was a baby. Once Isaiah got big enough to know what gentle meant we allowed him to pet Georgie with supervision. It took a little getting used to for Georgie he has always been our spoiled furball. However, Isaiah is now 5 and they get along great
I think just making a conscious effort when you can to spend time with Teddy will help and eventually everyone will settle in just fine
