Confession time!!

Ok, so I don't know how I'm supposed to describe what's going on with me but I think it's anxiety? Every time I think about having another baby other than my son, my heart starts pounding and I feel sick. I don't know if it's because I had a c-section and I have some hidden feelings about it or if I'm just super attached to my kid but it really sucks. I see other mothers with 2+ kids and I'm like "awe, her kids are adorable" but then I think about giving my son a sibling someday and I feel like I'm going to hyperventilate. I know I'm definitely not ready for another baby right now since my little one is only 6 months old but someday I would think that I want to. Will this feeling go away with time or will I always be terrified of taking care of 2 kids? 😳😣
