Disposable Diapers vs. Cloth Diapers

When choosing between disposable and cloth diapers, parents should decide how important sustainability and biodegradability are to them. Even the most natural disposable diapers are not fully biodegradable. 

Second, size matters. Diapers for toddlers over 50 lbs can be challenging to find. Parents may have one-size cloth diapers. The best cloth diapers for toddlers will be adjustable, flexible, and provide maximum absorbency. 

When looking at diapers for 2-year-olds, consider how easy they are to get on and off your toddler. Busy toddlers don’t like to lie still for diaper changes, so if you’re opting for cloth, an all-in-one is the most uncomplicated style to take off and put on. 

How to Choose the Best Toddler Diapers? 

When deciding on your toddler’s nappies, you should consider sizing, price, sustainability, and whether they are biodegradable. In addition, look at the ingredients to ensure they are chemical-free.

Sizing

Finding the best diaper for an 18-month-old is sometimes a challenge for parents. When your baby reaches a year and a half, their weight and height could vary significantly from their sibling or cousins.

To achieve the perfect fit, you need to pay attention to your baby’s weight, length, and where they carry their weight. Read reviews on diaper sites to see what other parents say about fit.

Hypoallergenic

Toddlers still have sensitive skin like younger babies, so it is important to have diapers that are gentle on delicate skin. In addition, toddlers may have developed substance allergies like gluten or fragrances or skin conditions like eczema.  Therefore hypoallergenic diapers are the best option to prevent diaper or contact rash. 

Biodegradable

By the time your child reaches the age of two, they will have worn 3,000 or more diapers. Unfortunately, conventional disposable diapers are not biodegradable and, at best, will take hundreds of years to decompose.

If you choose disposable diapers looking for ones that are at least partially biodegradable can help the environment. In addition, partially biodegradable diapers use more natural ingredients, which are better for your baby’s bottom.

Wetness Indicator

A wetness indicator may not be essential for older kids, for example, on diapers for toddlers over 40 lbs, because by this point, they can typically communicate when wet. However, if you have a non-verbal child or a child who resists diaper changes, you might want to look for diapers with this option. 

Free of Chemicals

Nobody wants chemicals on their baby’s bottom, so it’s a good idea to read the diaper packaging and look at the ingredients used.

While there are no disposable diapers that are 100% natural, the ingredients used can vary widely. Brands that use some natural ingredients are less likely to use harsh chemicals that could irritate your baby’s bottom. 

In addition, toddlers spend more time between diaper changes because they don’t go as often, so it is crucial to have the most gentle ingredients possible. 

Sustainability

Disposable diapers add to landfills and contribute to pollution when not made or sourced responsibly. By the time your child is a toddler, they will have used lots of diapers, so using a company that uses sustainable practices can reduce your child’s carbon footprint right from the start!
