Wakes up early

Akachan has been waking up for morning feed at around 5am this few days. He refused to get back to sleep after milk but happily played around. This is making Sarah and me extremely tired. It seems like the nightly power feed is losing its effect anymore. Or is it that Akachan's appetite has grown and we need to more to Akachan for his nightly feed? Hoefully this is just a passing phase and he will go back to a normal routine.

Its 5 am in the morning and Akachan is wide awake smiling at me.
