I feed according to how much is needed to maintain weight-some chins need 120ml a day, some need 60ml a day, some won't take more than 15ml at a time, some will eat 30ml at a meal-I start out with 4 15ml-20ml meals and weigh the chin daily, the same time each day, if the chin still loses I add additional meals, if the chin maintains I keep it at that. I use 10ml syringes, fill 2 at a time and I use a 50/50 critical care lifeline mix.
