This is a bit puzzling, but your baby probably feels full on smaller amounts of Isomil compared to Lactogen. He rapidly digests Isomil and within about 4 hours he is hungry again. This causes him to wake at 10pm. As he seems better on Isomil,he should probably continue on it. An alternative would be to try him on a low allergy cow's milk formula such as NAN HA.
