I feel like I failed

My week old baby is sick 😩 he has a runny nose & is warm. He caught my 2 year olds fever… I tried my best to avoid him getting sick. I sanitized, I didn’t let my 2 year old touch him. Ugh my poor baby 😔

* update *

I took baby in, he had no fever & she said to help his runny nose by bringing him in a misty washroom. Also to use a humidifier & his booger sucker thing lol. She took his temp rectally. Yay! I guess I just had him too bundled up why he was warm, idk.
