Worried about not being able to love this baby as much

So, I'm only 6 weeks along with this pregnancy. My son just turned 1 this week. He is my whole world, and I'm so nervous that when this baby is born I wont have the same love for it that I feel for my son.

I know it's super early, and I'm hoping that as my pregnancy progresses, and I start feeling movement etc that I will start to feel the same way as I did with my first.

I just love my little guy so much, I cant even imagine loving another baby like this. I feel terrible for even thinking like this 😥

Any other second time mom's feeling the same way? Or any third or more time moms with advice?
