Is It the Probiotic Time of Year?

Every year around this time, I start to notice a pattern — I call it “the probiotic time of year.” What do I mean by that? It’s when I hear from lots of families telling me their previously perfect sleeper — baby or toddler — has suddenly started waking during the night or rising far too early in the morning.
When I send them my famous list of questions to get to the bottom of the issue, a common theme emerges:
- A breastfeeding mum has recently started taking probiotics, or
- The baby or toddler has had a cold, ear infection, sore throat or chest infection and has been on antibiotics (and sometimes Mum has too).
What usually happens next is this: someone — a doctor, chemist or friend — suggests taking a probiotic to “support gut health” after antibiotics. While that may work well for some, I want to remind you that I tend to hear from the families for whom it hasn’t worked.
In case after case, I find that either:
- The breastfeeding mum is taking probiotics,
- The baby is taking them directly, or
- A toddler has started a probiotic supplement.
And again and again, once we remove the probiotic — within 48 hours — we have a happy, settled baby sleeping soundly again.
Not All Probiotics Are Created Equal
An interesting perspective I read from a children’s hospital stuck with me. They said choosing a probiotic should be like choosing a puppy — you wouldn’t just go out and buy one without doing your research. You’d look into the breed, their temperament, needs, and how they’ll fit into your family. It’s the same with probiotics. You need to know:
Which strain you’re giving,
- What that specific strain is meant to help with, and
- Whether it’s appropriate for your baby.
Probiotics do have their place — particularly in special care nurseries where specific strains may help with weight gain or gut support in premature or unwell babies. I’m not saying never to use them — but those probiotics are carefully chosen and used under medical supervision.
For most families, probiotics are not prescribed — they’re usually recommended by a well-meaning friend, chemist, or even a GP. But unless you’re really clear on the strain, its purpose, and how much to give, I suggest proceeding with caution.

A Word of Caution for Everyday Use
I truly believe that in years to come, we may look back at the widespread use of probiotics in babies — particularly in infant formula — and regret it.
We’ve seen it before: a parenting trend becomes the norm, only to later be reconsidered when more research emerges. I believe probiotics might become one of those trends we question.
Think about this: a probiotic supplement is usually designed to be taken once or twice a day. But if your baby is drinking infant formula with added probiotics — and is feeding 8 to 10 times in a 24-hour period — how much probiotic are they actually getting? That’s a lot more than the intended amount.
What I Recommend
If your baby’s sleep has taken a turn for the worse and they (or you) are taking probiotics, it may be worth cutting them out and seeing if things improve.
I do not recommend infant formulas with added probiotics. The formula I recommend is A2 Platinum. If you’re wondering why I don’t recommend A2 Gold, I’ve written a blog post explaining why — click here to read it.
