Cluster Feeding? Day 9?

So we've been warned that babies go through periods called "cluster feedings". It basically means that they eat more than normal and eat more often, and they won't quiet down until
they've had enough. Andreas is being fed "on-demand" anyway...and typically he drinks about 200 ml every 4 or 5 hours. Well, today he has been a little "off-schedule", which made mommy and daddy more tired. =( At 5 pm, he woke up and started crying. I changed 4 diapers until 6:30 pm and I fed him 175 ml of milk. He was still not satisfied. He wouldn't fall asleep. I massaged his arms, tummy and legs. He seemed to enjoy that. But then he started crying again.
S. just came back in time from buying a small refrigerator. So he took turns at burping him and feeding him another 120 ml. He finally fell asleep at 8:30 pm. Mommy was very tired!
