How to know baby is getting enough milk (what actually matters)
One of the biggest worries in the early days is whether your baby is actually getting enough milk.
It’s not always obvious — especially when you can’t see how much they’re taking in.
But there are a few simple things that give you a clear answer without overthinking it.
Wet nappies (the biggest clue)
Wet nappies are usually the clearest sign that feeding is working.
In the early days, you’ll see them gradually increase, then from around day 5 you’re looking for about 5–6+ a day.
It doesn’t need to be exact — it’s more about consistency.
If nappies stay low, it can sometimes mean baby isn’t getting quite enough milk yet.
The main signs to look for
You’re not looking for one perfect sign — it’s the overall pattern that matters.
The main things to look at are:
wet nappies increasing
weight going up over time
baby seeming settled after most feeds
If those are all there, things are usually on track.

What helps: Products I actually used
Breastfeeding pillow. Made longer feeds much more comfortable and easier to stay in a good position
MomMed wearable breast pump. Really good for a wearable — I got similar output to my wired pump
Lansinoh Anti-Colic Bottles. Helpful if you’re combining feeding, and designed to support a more natural latch
Spectra wired breast pump. Stronger than most wearables and useful at the start when you’re establishing supply — hospital-grade pumps can also be rented, but over time it can work out similar to just buying one
Weight gain (don’t overthink it)
Weight can feel like a big deal, but it’s more gradual than people expect.
Babies often:
lose a bit of weight at first
then start gaining again
What matters is the trend over time, not one single number.
Baby’s behaviour after feeds
After a feed, most babies will:
relax
come off naturally
seem more settled (even if it’s not for long)
It doesn’t mean they’ll be calm all day — especially in the early weeks.

Final thought
It’s easy to second guess everything in the early days, but you don’t need perfect measurements to know things are going well.
Look at the overall pattern — nappies, weight, and how your baby seems after feeds.
That usually tells you more than anything else.

FAQs
How long does it take to increase milk supply?
Usually not instantly, which is the frustrating part. Most people notice small changes after a few days of consistent feeding or pumping, but bigger increases can take a couple of weeks depending on what’s affecting supply.
What actually helps increase milk supply?
The biggest thing is milk removal — feeding, pumping, or both, more frequently. Things like hydration, eating enough, breast compressions, and not skipping night feeds can help too, but frequency is usually the main thing.
Do wearable pumps work as well as wired pumps?
They can work well for some people, especially for convenience and extra sessions. But stronger wired pumps are often better when you’re actively trying to build supply because they usually empty the breast more effectively.
Are lactation snacks and drinks enough to boost supply?
Not on their own usually. They can be a nice extra, but they won’t magically increase supply if milk isn’t being removed often enough. A lot of the marketing around them makes them sound more powerful than they actually are.
Is low milk supply always permanent?
Not necessarily at all. A lot of supply dips improve with consistency, extra feeds or pumps, and time — especially in the early weeks. But it’s also okay if breastfeeding ends up looking different to what you originally planned.
