Yes, actually, I am a mechanic who works on g-tubes. They can be funny little things. Mostly they cooperate, which is really good since that is what keeps my daughter nourished and growing!
We give Little Miss bolus feedings, rather than using a pump. It gives us more freedom and takes less time. Plus it mimics eating in that her stomach gradually fills over 20 – 25 minutes and allows her to feel hunger between meals. This practice supports our goal to increase her self-feeding. Currently her self-feeding (otherwise known as eating like other people) is at zero. It waxes and wanes. Drat.
Little Miss receives three meals and one snack per day – timed as much as possible to coincide with the family meals. The protein/veggie recipe is used for the three meals. Fruit/grain recipe is given at snack time.
Feeding a meal starts with the timer. A 60 ml (2 ounce) syringe is given at 3-minute intervals. Each time I hear the buzzer, I reset it for 3 minutes and begin feeding a syringe to Little Miss. I take 20 seconds to empty one syringe. This gives her tummy time to respond to feeding and accommodate the food (rather than cause reflux). It is important to make feeding a relaxed, gentle process. If rushed, of course vomiting can be the end result!
Eight of those syringes, for a total of 16 ounces, is adequate caloric intake for her age, size, activity level, and stomach capacity. (Little Miss is nearly 11 years old, 75 pounds, busy!! and had 10% of her stomach removed during a surgery.)
So, it looks like this:
8:05 1st 2 ounce syringe
8:08 2nd 2 ounce syringe
8:11 3rd 2 ounce syringe
8:14 4th 2 ounce syringe
Snack is the same, just a different food.
Meals are separated by 3 hours. So if breakfast is at 8:00 a.m., lunch cannot begin until 11:00 a.m. I allow at least 3 hours between the start of one meal and the start of the next meal to allow for digestion.
However, the fruit/grain snack is more quickly digested and I am able to begin her last feeding of the day 2 hours after snack.
