Kara's right. If he keeps waking, especially at random times over a few nights, it would be worth giving the night feed. Keep it as boring as possible... no talking, no eye contact, just feed, burp, and back down.
Or, if he hasn't woken in the MOTN lately, feed more frequently during the day. My son did both, increased frequency during the day, and needed an extra feeding at night.
Before starting that though, how did last night go? And he does get a hearty 35oz already. What do you think?
