You will definitely need to sacrifice a bit of your time with the younger one for the elder one now.
I have 2 kids too - 2.5 years old and 11 months old. I totally know how it feels, I had my elder child misbehaving and casting me aside at some point in time.

He kept throwing tempers and rejected me many times when I tried to be closer to him, and it hurt me really bad, but I continued to show him that I care for him and that I'm always there for him. And now we are close again, but of course my time with the younger must be sacrificed.
