Am I the only one?!

So my husband and I are currently ttc no2, I’m excited and can’t wait to have another gorgeous little bubba..... however, I feel sad and guilty that I’ll be taking my time away from my son, that I won’t have as much time for him or be able to play with him as much. That he will be upset and not feel loved as much. I’m not even pregnant yet and I feel like crying about it. My husband thinks is because I’m an only child and I never had to share my parents? I’d like to hear people’s thoughts!
