This is the central question. If your baby is waking because they're hungry, they need to eat — no strategy changes that. If they're waking out of habit (a sleep association with feeding), the approach is different.
Signs it's hunger: baby takes a full feed (3-5 oz or a full breastfeed), goes right back to sleep after eating, and the wake-up time varies based on when the last feed happened. Younger babies, underweight babies, and babies going through growth spurts are more likely to be genuinely hungry.
Signs it's habit: baby takes a small amount and falls asleep during the feed, wakes at the same time every night regardless of when the last feed was, and needs feeding specifically to fall back asleep (not just food). This pattern often develops after 5-6 months when caloric need at night has decreased but the feeding-to-sleep association persists.
Tracking feed volumes and times for a week makes this distinction obvious. Without data, you're guessing.
