Why does my newborn want milk again so soon?

Is on demand right at the beginning

We asked it plainly, and then immediately stress-tested it: what if she wants it more often than every two hours?

That second question is the one everybody actually has. On demand sounds relaxed until you're living it, and then it sounds like a baby who has never once been satisfied.

What it actually means

Watching her instead of the clock. The early cues are subtle — rooting, turning her head, hands going to her mouth, stirring and fussing. Crying is a late cue, and a baby who has got to crying is much harder to feed than one you caught earlier.

Newborns feed a lot, and not on any tidy schedule. Bunches of feeds close together, often in the evening, are ordinary and aren't a sign that anything has gone wrong with your milk or your baby.

Wanting to feed again ninety minutes later doesn't mean the last one failed. Small stomach, fast digestion, and sometimes she just wants to be near you, which is allowed to be a reason.

The exception that was ours

On demand assumes a baby who wakes when she's hungry and feeds effectively. Ari was born at 33 weeks and came home on a plan, and a sleepy preterm baby who doesn't demand can quietly not get enough.

So for us the plan won. Minimum frequencies, measured amounts, and waking her when she wasn't asking.

We're saying this loudly because feed on demand gets handed out as universal advice and it isn't. If you've been given a schedule for a reason, that reason still applies at four in the morning when she's sleeping peacefully through a feed.

What we watched instead of the clock

Wet nappies each day. Weight over several days, not every tiny change on the scale. Papa was constantly asking whether Ari had gained enough, then explaining away a lower number because she had just done a poo. A feed, a wet nappy or a poo can all move such a small number, so the trend mattered more than one weighing. We also watched whether she seemed settled after at least some feeds and whether the feeds were effective, not just frequent.

When any of that slipped, we said so rather than working around it.
