second pregnancy blues

I am on the fence about having another baby. Part of me really wants two children but the other part of me is depressed about the idea of my baby no longer being "the baby" if you know what i mean. I believe it would benefit him to have a sibling but I just feel terrible because then I'll be taking time/attention away from him. He is my first and sometimes (please forgive me) i think "how could I possibly love another baby as much as i love this baby?" I forsee a lot of emotional distress if I get pregnant again. Did you go through this too? How did you overcome it? I got my period this morning and was equally disappointed and relieved. I feel horrible 😢 i tried to talk to my husband about it last night but he just got angry and said "dont have another baby then!"
