Am I wrong for this? (Long post)

So I had been dating my child’s father for 3 years before I got pregnant. When I got pregnant, the only people that were really honestly supportive was my mom and a few family members on my side. Eventually when things started to kick into gear like baby expenses to prep for the baby, he didn’t have the money for it. He claimed he just didn’t have the money for it, after pressing the issue for a while he eventually spent $85 at Walmart on baby clothes. Which was fine, but that ended up being the only thing he ever got the baby. His “expenses” were buying weed to smoke, he never made our baby a priority. Whenever he would get money, he’d just spend it all on weed. When I was 7 and a half months pregnant, I found out he cheated on me with another girl because I was put on bed rest for a month after having a terrible kidney infection that left me in the hospital for a week. He had unprotected sex. Which hurt me because he was putting me and our son at risk to contracting whatever he could’ve gotten. I was livid, but I broke up with him. His family had always claimed to be excited, that they were looking forward to the baby. I had vented to his sisters about how he was acting, they told me they would help me with as much as they could. His mom even said she was gonna throw us a baby shower, she took me venue looking too just to get my opinion on what I liked what food I wanted cooked and everything (she does catering). They wanted to do this for me because they knew that my child’s father wasn’t really there and they wanted me to feel like I had a support system on their end. After breaking up with my child’s father, it’s like the family cut ties with me too. His sisters wouldn’t answer my texts or calls. I would text them asking how they were. His mother would leave my messages on read, they never threw me a baby shower. They just flat out dropped me off the face of the earth, which is fine. I ended up being the one to buy every single thing for my child. Clothes, Crib, Rocker, Car Seat, Stroller, Diapers, Wipes.. literally everything with the exception of that $80 worth of clothes he got him at Walmart which wasn’t honestly a lot it was 4 newborn outfits, a pair of mittens and a pair of socks. When I got to the end of my pregnancy, I moved in with my mom because my doctor put me on bed rest and I was dilating I was 4 cm at 34 weeks, my cervix was low and soft. She put me on bed rest and my mom took care of me. I made it to 38 weeks and welcomed my baby. The only person that was there was my mom, I had to have a c section and be put under general anesthesia because the anesthesiologist said the back problem I had made it impossible for me to have a spinal or epidural. It was rough for me, but the only person that stood by me was my mom. Being under general anesthesia was rough because the first day I barely have much recollection, I was so groggy, drugged up, trying so hard to be awake enough to at least hold my baby but couldn’t. Day 2 was different though, I was more awake and I had texted my child’s father and told him the baby was born, I got no response. Once I got home and settled, I had posted a picture on my Instagram of his little feet announcing his arrival. His sisters saw that post and ever since then they’ve been pissed. They were mad they weren’t there, they were mad they didn’t know I was in labor.. they’re mad they couldn’t come see him in the hospital and they want to come see him because that’s “their nephew”. I’m only 2 weeks postpartum. I’m still in alot of pain, my mom returned back to work because she couldn’t stay away too long and she took care of me the first week. Am I wrong for not allowing my child’s father’s sisters & his mom come see the baby because they ghosted me during my pregnancy and lied to me and dropped me off the face of the earth because we broke up? They’ve been so mad that they’ve even made posts on Facebook saying I’m being “scary” and “hiding my son” from the “world” because I won’t post pictures of his face and won’t let them see him because the child probably doesn’t belong to him. Please let me know your opinions ladies, I feel like I’m doing the right thing & keeping us away from them. & by the way, no he hasn’t tried to see the baby, it’s just the mom & sisters.
