How do I know if my baby is drinking enough?

This is the question that gnaws the hardest in the first weeks, and the hardest to answer yourself. You can't see how much goes in, and everyone has an opinion about it.

The four check-ins

Frequency. In the first month, eight to twelve feeds per 24 hours should go in, a good one about every two to three hours. If you're structurally below that, that's the first signal.

Sound. You hear the swallowing. That seems too simple to count, but it's one of the most reliable things you have: audible, rhythmic drinking means something is really coming in.

Diapers. Six or more wet diapers a day. This is the proof that what went in comes out the other end.

Stools. Soft and runny with breastfeeding, somewhat thicker with formula.

And on top of that is the answer that weighs most: a growth curve that rises. That's what your pediatrician keeps track of, and it's why those weigh-ins matter more than any calculation.

Feeding on demand, not by the clock

The advice from the hospital and from the pediatrician is the same for a reason: feed on demand. That means you respond to the hunger cues instead of a schedule.

Why that works better: it stimulates a healthy milk supply and fits growth. If you feed strictly by the clock, you ignore the subtle signals and sometimes feed too often, sometimes too little.

Those cues come in layers, and above all you want to learn to recognize the first ones. Early and subtle: smacking, rooting, hands to the mouth. Middle: stretching, wiggling, more restless movement. Late: crying. At that last point it's really already too late, and then feeding is harder too. See what your baby's crying means.

If you're unsure what's going on, go through SOAR: stop, observe, breathe, and only then respond.

The first two weeks are the hardest

Feeding is a skill you learn together. With breastfeeding, you're both learning: latching, sucking well, and meanwhile your milk supply has to get going. It gets sore, mastitis can come into it, and it's hard.

With bottle feeding there's plenty to learn too. Which bottle fits depends on the tongue, the lips and the way of sucking, and that isn't something you can see on the box. Kyra herself assumed the bottle that worked for her oldest would also suit her second; a lactation consultant saw from Celeste that a different bottle was better.

Look for help sooner than you planned

If you're unsure about the amount, if there's pain, if latching is hard: go to a lactation consultant, your family doctor or your pediatrician. They have the specialism, and knocking early is exactly what makes the difference between keeping going and stopping.

Bring your log. When there was a feed, how long, how much: that makes such a conversation concrete in one go. See also how much your baby should drink for the rule of thumb.
