Quick answer: A BabyWeigh scale is a highly accurate infant scale originally made by Medela for test-weighing breastfed babies, weighing before and after a feed to measure milk intake. For home use, the best baby scales in the UK in 2026 combine 5g accuracy, a hold function for wriggly babies, and a tare function. We compared the 10 top-rated options on Amazon UK below.

What Is a BabyWeigh Scale?

The BabyWeigh scale was developed by Medela as a hospital-grade infant scale for one specific job: test-weighing. A test weight means weighing a breastfed baby immediately before and immediately after a feed. The difference is the milk transferred, measured to the gram. Lactation consultants and breastfeeding clinics still use this method to check whether a baby is feeding effectively.

Original Medela BabyWeigh scales are clinical devices costing several hundred pounds and are usually rented through breastfeeding support services, not bought. For most parents, that level of precision is unnecessary. A good consumer baby scale with 5g divisions and a hold function handles weekly weight tracking, and informal test-weighing, at roughly a tenth of the price.

That is what this guide covers: the 10 best-selling baby scales on Amazon UK right now, compared on the specifications that actually matter for parents. I have spent a lot of time around weighing equipment, and with baby scales three things matter far more than everything else: the division size, a hold function for wriggly babies, and a tray that keeps them safely in place. The reviews below are scored on exactly those things.

How to Choose a Baby Scale: Buying Guide

Illustration highlighting key baby scale features: curved weighing tray, backlit LCD display, tare and hold buttons

Accuracy: 5g vs 10g divisions

The division size is the smallest change a scale can display. Newborns gain roughly 150–200g per week, so a 5g scale shows meaningful day-to-day movement and is precise enough for test-weighing. A 10g scale is perfectly adequate for weekly tracking of babies over a few months old. Anything coarser than 10g, like the 100g divisions on multi-use family scales, cannot track infant growth and should not be bought as a newborn scale.

Hold function: essential for wriggly babies

Babies do not lie still. The hold function (sometimes called weight lock or stabiliser) freezes the reading once it settles, so you can lift your baby and read the result at leisure. If your baby is under 6 months, treat this as a must-have feature.

Tare function: weigh with a blanket

Place a muslin or blanket on the tray, press tare, and the scale zeroes it out. The reading is then your baby alone. Every scale in this guide has it, and you should not buy one that doesn't.

Capacity: 20kg covers birth to toddler

A 20kg capacity handles babies from birth to around age 4–5. Higher capacities (100kg+) mean the scale doubles as a family or pet scale, but usually at the cost of finer accuracy. Check the division size, not just the headline capacity.

Display: backlit is worth it

You will weigh your baby at odd hours. A backlit LCD is readable in a dim nursery without turning lights on and waking the baby. Larger digits (20mm+) help when you're reading over a squirming infant.

Memory and apps: nice, not necessary

Last-weight memory lets you compare readings without writing them down; Bluetooth apps draw growth curves automatically. Both are conveniences. Your red book and health visitor do the clinical tracking. Don't pay double for an app if a £45 scale meets your accuracy needs.

How to Do Test-Weighing at Home

Illustration of the three test-weighing steps: weigh baby before feed, breastfeed, weigh baby after feed

Test-weighing is the technique BabyWeigh scales were designed for: measuring how much milk a breastfed baby takes in a single feed. You need a scale with 5g divisions or finer and a hold function. Your first few attempts will probably give jumpy numbers. That is normal, babies never lie still, which is exactly why the hold function matters.

  1. Place the scale on a hard, flat surface and switch it on.
  2. Weigh your baby in a dry nappy only (or naked). Note the weight, then use the hold function.
  3. Feed your baby as normal, without changing the nappy.
  4. Weigh again immediately after the feed, in the same clothing.
  5. The difference is the milk transferred. 1g of weight gain ≈ 1ml of milk.

Important: a single test weight is a snapshot, not a verdict. Intake varies feed to feed. Do 2–3 test weights across a day for a useful picture, and always discuss results with your health visitor, midwife or a lactation consultant rather than making feeding decisions alone. If your baby is not gaining well, seek professional advice promptly.

How to Weigh Your Baby Accurately

  • Same conditions every time: same time of day, undressed or in a dry nappy, before a feed.
  • Hard flat surface: never on carpet or a soft changing mat. It skews readings.
  • Weekly, not daily: daily weights bounce with feeds, wees and poos. Weekly trends are what matter.
  • Record it: note the date and weight in your red book (PCHR) so your health visitor can plot the centiles.
  • Convert units if needed: health visitors work in kilograms. Use our kg to stone converter if your scale reads in kg and you think in stone.

Our Research Methodology

How we researched this guide: we ranked Amazon UK's best-selling baby scales in October 2026, then compared the specifications of the top 10 (accuracy divisions, capacity, hold/tare functions, display and power) against manufacturer listings. We analysed aggregated themes from 20,000+ verified customer reviews for recurring praise and complaints, and checked live prices in October 2026. We did not receive free products from manufacturers. We have not hands-on tested every model; our judgments combine published specifications with aggregated buyer feedback. Prices and ratings change, so we re-check them before each update.

Frequently Asked Questions

What is a BabyWeigh scale used for?

A BabyWeigh scale is a highly accurate infant scale originally made by Medela for test-weighing breastfed babies, weighing before and after a feed to measure milk intake. Home baby scales with 5g accuracy can do the same job for everyday monitoring.

How accurate are baby scales?

Most digital baby scales sold in the UK measure in 5g or 10g increments. A 5g division is precise enough to track newborn weight gain and test-weighing; 10g scales are fine for general weekly monitoring of older babies.

How often should I weigh my newborn?

For healthy term babies, once a week is plenty; daily weighing shows normal fluctuations that cause needless worry. Weigh at the same time of day, undressed or in a dry nappy, and plot results in your red book. If you have concerns, speak to your health visitor or GP.

Can I use a regular bathroom scale to weigh my baby?

You can estimate by weighing yourself holding the baby and subtracting your own weight, but bathroom scales typically read in 100g increments, too coarse to track newborn gains. A dedicated baby scale with 5–10g accuracy is far more useful.

What is the hold function on a baby scale?

The hold function freezes the displayed weight once the reading stabilises, so you can lift a wriggly baby off and still read the result. It is one of the most useful features on a home baby scale.

Are cheap baby scales accurate enough?

Many budget scales under £45 offer genuine 5–10g accuracy and hold/tare functions. What you give up at lower prices is usually build quality, app features or brand support, not necessarily accuracy. Check the division size in the specifications, not just the price.

Final Verdict

Best overall: the Chicco Digital Baby Scale: 8,200+ UK ratings make it the most proven pick, and the stabiliser system handles wriggly babies well.

Best for precision on a budget: the Beurer BY80 or LAICA: genuine 5g accuracy under £47, good enough for test-weighing.

Best smart scale: the Beurer BY90: Bluetooth growth tracking plus an integrated measuring tape.

Closest to a real BabyWeigh: the seca 354: its breast-milk-intake function automates test-weighing. At ~£200, though, it's for medically-advised use, not casual monitoring.
