Baby #2 help..

Sierra • Hello, my name is Sierra. My son is 10 months old now and my husband and I are trying for baby number two 🎉😍
I have a 6 month old son. SO and I were not trying but I think I may be pregnant with #2. I'm nervous to have another that my son may feel left out or like we have replaced him. I'm worried that I will feel guilty for having another baby. Are these normal feelings? Please any advise would be nice!
