If I assist feed, I don't offer again for a week. If they are eating normally, I feed every three days up until around 300 grams, then go to five days up til 1000 grams. If they are assist fed, I wait a week then try a regular feeding, if that doesn't take, keep an eye on the weight and try again in three days. If there is a weight drop, I assist feed again. If it is a very small baby, I may assist feed quicker. It really depends upon the size and appearance of the baby. I have a few that I've raised that had to be assist fed more than ten times. The good news is once they got over their slow start, they became great eaters.
