What's the main difference between a growth spurt and a sleep regression?

A growth spurt is usually described as a few days of clearly bigger appetite, often with evening cluster feeding. Rough sleep with no change in appetite, longer wake windows, less day sleep and early mornings points more towards the routine side, which is what the tool counts as schedule pressure.

We have more night wakes but no cluster feeding. What does that suggest?

If appetite is flat and there's no cluster feeding, the tool leans routine-driven. Try a 2–3 day reset: trim wake windows by 10–20 minutes and keep bedtime steady.

Do early-morning wakes point to a schedule problem or a spurt?

They can happen with both, but the tool counts early waking towards schedule pressure, especially alongside low day sleep and long wake windows.

How do travel, heat or vaccines affect the result?

Any recent disruptor adds a point to schedule pressure. Settle the environment first (room temperature, light, noise) before making big routine changes. The NHS notes teething and illness can affect sleep too.

The rough patch is 5+ days. Could it still be a spurt?

The tool treats 5 days or more as pointing away from a spurt, since growth spurts are usually described as lasting a few days. Do a short reset and review the room. If you're worried, or your baby seems unwell, speak to your health visitor or doctor.

Does fever ever fit a growth spurt?

No. Fever points to illness. For a baby under 3 months, 38°C (100.4°F) or higher needs medical advice straight away. For 3 to 6 months, the NHS says to call 111 at 39°C or higher.

My baby was born early. Does that change anything?

The tool doesn't use age, so it works on the signs either way. Premature babies often have specific feeding and sleep advice, so follow what your neonatal team or health visitor has told you.

How many days should the pattern last to count as a spurt?

Health services describe growth spurts as lasting a few days. The checker gives the most weight to a 2–4 day pattern and treats 5 days or more as a sign to look for other causes.

What if diapers are lower than usual?

That's a warning sign, not a growth spurt sign. Fewer wet diapers than usual can mean dehydration, so the NHS advises an urgent GP appointment or NHS 111. From day 5, a breastfed baby should have at least 6 heavy wet diapers a day.

Can formula-fed babies have growth spurts too?

Yes. Any baby can go through phases of wanting more. With formula, offer smaller, paced feeds and follow your baby's cues rather than pushing larger bottles. The NHS warns against overfeeding.

Can I use it for twins?

Yes. Run the checker separately for each baby, as their patterns often differ.
