IT is very doable.
DS was 7 almost 8 when we did EEN over thanksgiving/christmas.
IF he is drinking orally- I would recommend these

SO they can be kept in the fridge at school and no one knows (ie classmates) that he is on formula.
We did two pepatamen junior in the morning. Two for lunch ( filled one water bottle) then two for dinner with a before bed snack of one shake.
He was very full all day from that.
HE aslo had water during the day.
We got the ok from the GI to let him have pure sugar (ie dominos) and dum dum lollipops since kids with EoE (similar gut rest) are permitted these things.
With pure sugar I was able to make cotton candy.
Here is a cheap machine

This meant I could make Cotton candy cupcakes for treats to take to school /birthday parties plus his birthday.
He had a no foods cake.
Two boxes decorated with lots of hand wrapped trinkets inside candle on top to look like a cake.
We also made sugar cookies.
Sugar + water +silicon mold= sugar cookies for christmas:thumright:

DS has life threatening food allergies so the school never ever gives him any food- I would insist on a note from the doc to educate the school.
For chewing skills- WE had a piece of gum but mainly snow cone shaved Ice I would prep at dinner for him to chew with his drinks. We also added a small amount of sugar if he wanted.
He may have had about 3-4 tbsp of sugar extra a week not a daily thing.
Drinking it was hard in the beginning taste wise but we treated like all his other meds not really a choice. He survived thanksgiving, christmas, his birthday and valentine's day so it an be done.
It was the best he felt was well.
Do not be surprised if he has liquid stool. It does not hurt and is not true diarrhea just liquid in = liquid out in most kids.
good luck
let me know if you have any questions.
