Update on audriannas gi appointment

So we went to the gi appointment today for audrianna. The nurse first weighed audrianna with her diaper which was slightly wet, her jeans, and a long sleeved shirt on Audrianna weighed in at 28lbs 1 oz then because I didnt think it was accurate how could it be audriannas not eatting much. So we stripped her down completly and weighed her again 27lbs 1oz a whole lb difference. Anyways the gi dr comes in we talk, he askes how she was eatting and i told him about how she eats at home and school the school writes down exactly how many bites and how many oz. The gi dr decided its best that audrianna get a feeding tube put in first we discussed a ng tube but since she tried to rip it out when she was hospitalized we decided not the best option. So now we have an appointment with the pediatric surgeon on march 2nd at 4pm for a gtube evaluation. Audrianna will be getting a gtube. I don't know alot about what to expect if anyone has a kid with a gtube please clue me in cause well i am clueless
