No visitors , mom is sad

So my daughter is 11 days old , the day after she was born I had visitors in the hospital , and about two days after being home I let my mom and mil come over and see baby. Well she caught rsv at day 5 and was admitted in the hospital for three days, seeing my poor baby go through that my hubby and I agreed to have no visitors until she is a little bigger. Everyone is respecting my wishes except my mom. She's saying she don't deserve to be treated this way , I told her it's nothing personal I just want to wait, she thinks I'm being ridiculous because I said maybe when baby is 3 months old , she's acting like I'm personally attacking her and I feel bad but it's my baby and that's what I want to do. Am I being over protective or ridiculous? Or is my mom just being selfish
