Guilt?

Shelby • I`m the mother of 2 amazing toddlers, both boys. (1yr & 3yrs). pregnant with #3 and this one is a girl <3
I've always wanted 2 children. Ever since my nephew was born when I was 8yrs old, I knew I was born to be a mom. I had my first baby in June of 2013. I just found out Im pregnant with #2 & due in November this year. My son loves babies & is very compassionate & considerate for his age, and while I was excited at first, now I have an overwhelming sense of guilt. I dont want my son to think I dont love him, or that I love the new baby more. I feel guilty for adding another baby to the family when he is used to my undivided attention. Anyone else feeling the same?
