Hi
The cans of food can be very filling, maybe and this is only a suggestion, try to get the fluids in him first, when I was gravity fed I threw up everywhere I had to use a syringe and a feed would take about 20 mins, please note I only had surgery.
When my Mum was on strong painkillers she needed a few enemeas to sort her constipation, talk to the medics, they should be able to sort that..
I hope someone better placed than me can also help..
Sunshine... love and hugs
Helen
