god kids and kids

I know this might sound weird but is it dumb I'm scared i won't love my own kids as much as I live my god son? I was the only one in the hospital with his mom when he was born , I was the first person he saw, I cut his cord, and I also took him home straight from the hospital and had him for a year with Every other weekend visits to his mom. I love him like my own and he's really upset at the news of me being pregnant and I'm scared i won't have the same bond with my kids if they aren't like how he was as a baby. is that dumb because I always been scared of this moment
