Struggling

My LO is a month old and Ive been breast feeding and everything is getting so overwhelming. Baby is cluster feeding, I have a 7 year old running around needing attention but I feel like baby is glued to me 24/7 so I can’t tend to my other baby the way I should be and that makes everything harder. I hate having to tell him to hold on or I’ll do it in a minute. That breaks my heart 🥺 My emotions are getting the best of me. I’m really struggling. If anyone else tries to hold baby he screams until I get him. Dad is incarcerated so that’s no help to anything going on. Im exhausted 😭
