Choose a diaper size by your baby’s weight, not their age. Every diaper pack sold in Kenya prints the weight range it fits, and sizes differ between brands. Move up a size when you see red marks on the skin, frequent leaks, or tabs that barely close. At Zawadi Baby Shop, diapers start from KES 500 as of September 2026.
This guide explains how diaper sizing works, when to move up a size, how disposable and washable diapers compare, and what parents commonly do to keep the diaper area comfortable.
What size diaper does my baby need?
Your baby needs the size whose weight range on the pack includes their current weight. Sizes usually run from a newborn size or Size 1 up to Size 5 or 6, and each brand sets its own weight ranges. A Size 3 from one brand may fit differently from a Size 3 from another.
If your baby’s weight sits where two sizes overlap, many parents choose the bigger size for a slim, long baby who is growing fast, or for night-time, when the diaper has to hold more. Weigh your baby at the clinic, then check the pack before you buy.
| What you notice | What it usually means | What to do |
|---|---|---|
| Red marks around the waist or thighs | The diaper is too tight | Try the next size up |
| Tabs only just reach the front | The diaper is too small | Move up a size |
| Leaks up the back or out of the legs | Wrong size, or the leg cuffs are tucked in | Pull the cuffs out; if it keeps happening, size up |
| Gaps at the legs, tabs overlap a lot | The diaper is too big | Go down a size |
| Fits well but leaks overnight | It is full before morning | Many parents use the next size up at night |
How do you know when to move up a diaper size?
Move up a size when the current diaper stops fitting comfortably or stops holding everything. Check for these signs at each change:
- Your baby’s weight is at the top of the range printed on the pack.
- The tabs sit near the sides instead of the middle of the waistband.
- You see red lines on the skin when the diaper comes off.
- Leaks happen often, even when the diaper is put on correctly.
- The diaper no longer covers your baby’s bottom fully at the back.
Babies grow quickly in the first months, so avoid buying many packs of the smallest sizes at once. Buy one or two packs at a time until you know how fast your baby is growing.
High back waistband and strong grip tabs. Check which sizes are in stock.

Are disposable or washable diapers better?
Neither is better for every family. Disposable diapers are quick and convenient, especially for nights and travel. Washable diapers cost more at the start but are reused many times, so you buy fewer over time. Many parents use both: washable at home during the day, and disposable for nights and trips.
| Disposable diapers | Washable diapers | |
|---|---|---|
| Cost | You keep buying packs | Higher cost at the start, then reused |
| Daily effort | Throw away after use | Rinse, wash and dry |
| Nights and travel | Very convenient | Possible, but you carry used ones home |
| Water and drying | Not needed | Needs water and a place to dry |
| Waste | More rubbish to dispose of | Much less rubbish |

What types of diapers are sold in Kenya?
Most diapers sold in Kenya fall into three types:
- Disposable tape diapers: the classic diaper with sticky tabs at the waist. They suit newborns and babies who are lying down for changes.
- Diaper pants (pull-ups): pulled on like underwear. Many parents switch to them when a baby starts rolling, crawling and wriggling during changes.
- Washable (cloth) diapers: reusable diapers with a waterproof outer layer, fastened with snaps or tabs, and washed after use.
Whatever the brand, the checks are the same: the weight range on the pack, a soft inner layer, leg cuffs that sit snugly, and tabs that hold without being pulled tight. You can see the diapers we stock in our diapers collection.
How many diapers will your baby use?
Newborns need changing every time the diaper is wet or dirty, so the first months use the most diapers. As your baby grows, changes become less frequent. The number varies from baby to baby, so plan with a simple sum rather than a fixed rule.
For example, if your baby uses 8 diapers a day, that is 56 a week. Divide by the number of diapers in your pack to see how many packs you need each week. Keep one spare pack in the next size up, so you are ready when your baby outgrows the current one.
How can you reduce the chance of diaper rash?
Change wet or dirty diapers as soon as possible, clean the skin gently, and give your baby some time without a diaper. The UK’s National Health Service (NHS) guidance on nappy rash recommends these steps, and suggests cleaning with water or fragrance-free, alcohol-free wipes.
If a rash causes discomfort, a pharmacist can suggest a suitable cream. Some parents use a barrier cream, such as our zinc and castor cream, at diaper changes. See your clinic or doctor if the rash does not get better, gets worse, spreads, or if your baby has a high temperature or seems very uncomfortable.
What should you keep in your diaper bag?
Pack enough diapers for the outing plus two spares, wipes, a changing mat, a spare outfit, and a small bag for used diapers. A diaper bag with separate pockets keeps clean and used items apart. For more ideas, read our guide to choosing a diaper bag, or browse our diaper bags.

Frequently asked questions
How do I know my baby’s diaper size?
Weigh your baby, then choose the size whose weight range on the pack includes that weight. Sizes differ between brands, so always check the pack. Red marks, leaks or tabs that barely close are signs it is time for the next size.
How much are diapers in Kenya?
At Zawadi Baby Shop, Rascals diapers cost KES 1,800 a pack and washable diapers start from KES 500, as of September 2026. Prices change, so check the product page for today’s price.
Are washable diapers worth it?
Washable diapers cost more at the start but are reused many times, so many families buy fewer diapers over time. They need water, washing and drying space. Many parents use washable diapers at home and disposable ones for nights and travel.
When should I switch from tape diapers to diaper pants?
Many parents switch to diaper pants when their baby starts rolling, crawling and wriggling during changes, because pants pull on like underwear. Use the same weight range on the pack to choose the size.
