Babies with bronchitis

Mommas i need help. Im really scared of my son being admitted to the Hospital this morning again for bronchitis. He had it a few weeks ago and Monday he started with the flu, i took him and they said it was more than likely allergies, they told me to take him back in 2 days so im taking him back today but he got worse. He has congestion, a really bad cough and he started wheezing and breathing really fast after midnight. Hes eating fine and sleeping good only wake up to eat and goes right back to sleep but i am really afraid of him getting admitted, last time he was in icu. If you have a baby with bronchitis history you know how horrible that experience is😔 is there any chance he can get medicine and come home? Im really hoping its not bronchitis again
