Did you feel like this with your second?

I’m pregnant with my second and I honestly have so much guilt. My son has been the most important thing in my life since he was made. Everything I did, was centered around him, everything I thought of, had to do with him, he is my pride and joy. I honestly never really thought about more children because I was just so focused on him and making him happy and being the best mom I can be. I was also only 18 when I had him, I was dead set on proving everyone wrong and being the best person and parent I could be. His bio dad and I haven’t gotten a long in awhile and I’ve had to fight tooth and nail for my boy. I never thought I could love anyone else as much as I do him. I feel bad that he’ll have to share the spotlight. It’s my worst fear to have him think he’s second best. I also fear that someone how this baby will think I favor my first son because I’m trying too hard for my first son not to feel that way. I’m only 12 weeks, so I think it will get better the further a long I get. I just can’t get over this guilt. I’m trying really hard to get my son excited to be a big brother, and he is! He wore his big brother shirt 3 days in a row straight until I had to force him to take it off to wash (don’t judge, he’s fine lol) he insists he wants a baby sister, not a brother, and he likes to hug my tummy while saying “the baby growin’ strong in there.”. Maybe I feel like this because I had reckless parents who never thought about their consequences to their acts and it really affected my siblings and I badly. Idk, I’m probably just being emotional as hell.
