Breast Milk - I want it fresh

Eethan seems to know when I'll be home.

He didn't want to drink his milk at night and will wait until I reach home.. If he's really hungry, he'll only drink 2-3oz then he'll push away his bottle. He'll get angry if being pressed to finish the bottle.

The moment I reached home he'll want me to carry and he'll start looking for fresh breast milk! I tried giving him the balance in the bottle when he is almost asleep. He used to finish it. But recently I think he has grown smarter. The moment the bottle touch his lips, he'll get angry and will start waking up.

To avoid him waking up, I've thrown away don't know how many ounces of unfinished breast milk.
