Congestion and wheezing 😭😭😭😭

For a good 6 months now my son has constantly been congested. hes had 4 early infections, wheezing, uses an inhaler, up all night screaming and cry, tubes in his ears and nothing is working. I just want my baby to be able to be a normal toddler but instead he constantly has snot pouring from his nose and turns into wheezing. the only time he's fine is when hes on antibiotics which the doctors are puting him on all the time and when he's not on them hes horrible they also have bim.on allergy medicine and nothings working. I wish I could just get an answer on how to stop this and trade places with him. im so lost at what to do and feel like.im the only mom going through this. 😭😭😭😭😭😭😭
