Thank you for your query on Healthcare Magic.
As the child is on steroids
and antibiotics, there may be a possibility of gastritis
development due to which the child may be having vomitings.
Steroid and most of the antibiotics usually cause gastric irritation leading to vomitings.
So these drugs should be given with feeding to lessen the gastric irritation.
And discuss this issue with your Pediatrician
and get medication for his vomitings and gastritis.
Hope I have answered your query.
