Infant Growth Chart: Track Your Baby's Development with Confidence

When you're new to parenting, an infant growth chart, a tool used by pediatricians to measure and compare a baby's weight, length, and head circumference over time. It's not just a line on paper—it's your early warning system, your progress tracker, and sometimes, your peace of mind. In the UK, health visitors and GPs use these charts to spot patterns, not just numbers. They’re based on WHO standards, not outdated averages, so they reflect how healthy babies actually grow—no matter their size at birth.

Related to this are baby growth milestones, key physical and developmental markers like rolling over, sitting up, and first words that align with growth patterns. These don’t always happen on schedule, but when a baby’s weight drops sharply while missing milestones, it’s a signal. On the flip side, rapid newborn weight gain, the expected increase in weight during the first few weeks after birth, typically 150–200 grams per week is normal—but if it’s too fast, it can hint at overfeeding or underlying issues. And then there’s infant development, the broader picture of how a baby learns to move, interact, and respond, which often mirrors physical growth. These four things—growth chart, milestones, weight gain, development—are linked. One doesn’t work in isolation.

You don’t need to be a doctor to read these charts. Most UK parents get their baby’s measurements recorded at 10 days, 8 weeks, 12 weeks, and 6 months. If your baby’s line stays steady on the 25th or 50th percentile, that’s perfectly fine. It’s the sudden drop or jump that raises eyebrows. And if you’re worried? Bring the chart to your next appointment. No judgment. No rush. Just facts.

What you’ll find in the posts below aren’t just random parenting tips—they’re real, practical answers from UK families who’ve stood in the same shoes. From how to interpret those squiggly lines on the chart to why your 3-month-old isn’t gaining as fast as the last one, from what’s normal after a tough start to how feeding styles affect growth, these articles cut through the noise. No fluff. No fear-mongering. Just what works when you’re holding a sleepy newborn and wondering if everything’s okay.
