Rude NICU nurse

I just had my son at 31+2 via c section 3 days ago so im hormonal and overly sensitive. I went down to the NICU to see him this morning and i was super excited because my mom and sister were coming to see him for the first time. His nurse was immediately rude as hell, didnt say hello didnt smile. Just said "are you mom?" And gave me a brief update on how he was which is fine! Then she went on to shame me for holding my son for too long last night even though his nurse last night told me i had to commit to holding him through his feed and for an hour afterwards so hes not over stimulated so of course i agreed and spent that time holding my son. She then went on to butt into mine and my moms conversation every 2 minutes about my daughter being a newborn, basically trying to make me feel stupid with everything i said. I eventually just shut up and stopped talking while she was in the room. Her bedside manner was just awful i felt the need to leave the NICU and go back up to my room. I might be overly sensitive right now but the tone of her voice and everything was just insanely rude and i couldnt handle that. All i wanted was to visit my son and let my mom visit for a bit but she made me so uncomfortable i had to leave. I hope i can stop being so emotional soon because he has a long way to go before coming home and im sure ill have to deal with a lot more of that.
