If the five year old will be hospitalized overnight, you need to prepare them for that. Perhaps a book like this one purchased beforehand and read to them several times.
Perhaps a new and special stuffed animal to act as their hospital guardian.
Forgot about the foods:
“What to Eat After Tonsillectomy Surgery
Fluids are very important the first 48 hours after surgery. Fluids should be encouraged, as surgery and the healing process can contribute to dehydration, even though the patient does experience pain when swallowing. Skip the ice cream for the first day, along with other dairy foods for the first 24 hours after surgery. Dairy products can make a film in the mouth and throat. Popsicles are an excellent alternative, as they are cold and soothing and help with the patient’s fluid requirements.
Avoid using straws while recovering from this surgery. It is very easy to poke or injure the surgical sites with a straw. For small children, a sippy cup is fine, as there is no risk of injury to the throat.
What to Eat After Tonsillectomy Surgery
Opt for these foods, which you may want to purchase before the surgery so you’re stocked up and ready:
* Cold Foods – The cold of the food may help with the pain and swelling. Popsicles, frozen fruit pops and sorbet are ideal.
* Soft Foods – Mashed potatoes, pasta, cottage cheese (after the first 24 hours), and soup.
* Juice, Water, Athletic Drinks, Punch- Remember, if it is very cold, it may help with the pain and swelling.”
