Your child will likely only need to be in the hospital for a day or two, depending upon how well he tolerates his feeds after, as well as your familiarity with tube feeding. The stay will be longer if a Nissen fundoplication is also performed.
Some hospitals will give Tylenol for pain, some Tylenol with codeine, and some will give narcotics. It depends on the specifics of your child’s surgery and surgeon preference.
The nurses or someone from your DME supply company should train you on how to do everything before your child is discharged. Be sure to try everything yourself, and to ask lots of questions to make sure you are comfortable.
Your child’s tummy may be a little sensitive for a while, maybe up to a few weeks. But once the stoma has healed, your child should be able to do tummy time again with no problems.
