Patient was born. He was born without any issues and was perfectly healthy. On October 20, 2022 we took him to his Pediatrician?s office because he had had a rash over his torso for 2 weeks and had now developed cold symptoms (runny nose, dry cough and sneezing). He saw a traveling Pediatrician that day and was diagnosed with a virus and viral rash. We were told to put Eucerin cream on the rash. We had stopped breastmilk a few weeks prior and were trying to introduce Nutramigen formula however at this time we started giving breast milk again and giving patient daily baths. One week later, on October 27, 2022, patient was due for his 2 month vaccinations. He had been given the Hep B at birth with no complications. His rash was better but he did still have cold symptoms, which did not seem to concern the Pediatrician. His temperature was 98.6. He was given 4 shots that day, Pediarix (DTap, IPV and Hep B), Prevnar #13, Hib and Rotateq. He seemed to do fine the rest of the day. He did have a screaming fit when he was being changed, like he was uncomfortable so we gave him 1.25 mL of Tylenol. He was restless and wouldn?t lay on either side but after the Tylenol he slept well all night. The next day, October 28, 2022 patient did well. He did seem uncomfortable in the morning so I gave him 1 mL of Tylenol and he fell asleep in my arms. I needed to start getting ready for work at 4 (from home) and his Dad got him at 3. He fed Patient (5 oz which he ate well) and walked around with him until he fell asleep, around 4:30. He laid him down in the bassinet in our room. Around 4:50 patients dad left to go get supper and I was making coffee, getting ready to start work. I watched the monitor from the kitchen (right next to the bedroom) and listened to him. At 5:15 patients dad got bak home and Patient woke up. It was normal for him to wake up every 45 min or so, and Patient fell back asleep. Between 5-6 he woke up again so Dad fed him another 2 oz and rocked him back to sleep then laid him down on his left side in the bassinet, where he slept for another hour. Patient started to stir again and seemed uncomfortable so Dad went in and moved him to his belly, which seemed to calm him down. There were not blankets in the crib other than the one he laid on and he had no pacifier. Patient was laying peacefully with his head turned to the side, one arm kind of underneath him and the other up by his face. Dad could tell he was asleep by his breathing so he left the room, leaving the door cracked open. He was outside on the deck cooking. 7:30 was the last time he checked in on Patient and could see everything was fine. At 9:00pm I finished work, pumped for about 15 minutes then went online for a few minutes. I saw the second green light on the monitor go on, which indicates noise so I went into the bedroom thinking Patient was stirring. (Our home is small, so the monitor picks up all noises). The fans were on and it felt a bit cool, so I went over and touched Patients right leg and it was freezing cold. He was face down, so I picked him up. I don?t know where the light was coming from, but I could see that he was already mottled. I went outside to patients dad saying, ?He?s gone, he?s dead?. I was trying to rouse him but he was already gone. While on the phone with EMT we put him on the new rug on the floor and started CPR. As we were giving him breaths I could hear the fluid. When the EMT?s arrived I had to go outside because I just couldn?t look at him like that. Just 34 hours after receiving his 2 month vaccinations my baby was gone.
