Different Pregnancy’s

Is it normal to feel a different emotionally with each pregnancy? I really am grateful and happy to be having another baby but at the same time I don’t feel as connected to this baby as I did with my first. I feel like when I was pregnant with my daughter we were so excited and that was all I ever thought about but this time I forget I’m even pregnant and when I do remember I get really nervous/overwhelmed about taking care of 2 kiddos. Not sure if it’s because I have a 10 month old that takes a lot of my time or because this pregnancy wasn’t planned but I feel really guilty for not being as excited as I was for my first😔
