Breastfeeding baby #2

Will my almost 3 year old feel less loved/less important if I breastfeed/ pump and bottle feed baby #2 as a pose to formula feed? Am I overthinking this whole thing? Baby #2 is due In two months and no matter how hard I try to convince myself, I don’t want to formula feed. I breastfed my oldest for almost two years and I see how good it was for him. I can’t imagine not giving the same thing to my next baby. I don’t want to feel like a bad mom to my oldest but I feel like if I formula feed, he will have more of my attention than if I breastfeed. But then I feel like a bad mom to baby #2 and I just don’t know what to do.
