Diaper ruffles should be out and not in when you change diapers.
When changing diapers always run your fingers around the ruffles or leg gathers to ensure the leg gathers or ruffles are out which helps prevent leaks around the baby's legs.
The diapers that hold the most pee for babies is Dollar General Gentle Steps diapers, Huggies Diapers, Pampers Baby Dry diapers, Amazon Mamma Bear diapers, Kirkland Diapers and Rascal and Friends diapers.
The best diapers that don't leak in my experience are Dollar General Gentle Steps diapers which I started using with my kids a few years ago.
I was using the more expensive Huggies Snug and Dry diapers and Pampers and found that "while they are very absorbent and are good diapers" that Dollar General Gentle Steps diapers are more absorbent and don't leak like Huggies and pampers did with my kids.
It is best for diapers to be too big than too small as diapers that are too small can cause red marks and irritate the baby's skin and be uncomfortable and also leak and not hold enough pee and poop.
When diapers are bigger they hold more and don't leak or irritate the baby's skin but you don't want the diaper to be too big so that it has gaps in the legs or falls down the baby's waist as it can leak.
A proper fitting diaper is essential for your baby's or toddlers comfort and for keeping their clothes dry and preventing leaks.
The size of diapers that toddlers stay in the longest is size 3 and size 4 diapers.
The diaper that is best for leaks is Gentle Steps diapers from Dollar General which I found are even better than Pampers baby dry diapers and Huggies.
Huggies is also a good absorbent diaper that does not leak for most babies and toddlers but after trying Dollar General Gentle Steps diapers on my kids I find they are much better than Huggies and Pampers Diapers.
They are also cheaper as well.
The size of diaper that babies stay in longer is size 3 diapers up until age 1 and then after that they tend to stay in size 4 until age 2 to 3 until potty trained.
However babies and toddlers are different weights and are built different so while one baby could fit in a size 4 at age 2 or 3 another baby or toddler of the same age may need a size 5 or size 6 diaper.
The majority of babies and toddlers wear size 4 diapers up until they potty train.
Size 4 diapers are for babies and toddlers from 18 months to 3 years of age or 22 lbs to 37 lbs.
Size 5 diapers fit children 4 to 5 years old and size 6 fits children 4 to 7 years old for some kids.
Size 7 diapers fits kids between 5 years old to 8 to 10 years old and sometimes older.
After size 7 diapers is a size 8 diaper which can fit kids from 8 years old to 12 to 13 years old and sometimes older depending on how much they weigh and their build.
As babies get older they pee less and need less diapers than younger babies.
By age 2 to 3 years old most kids only need a diaper change every 3 to 4 hours depending on how much and how often they pee.
While the diaper size may appear to fit your baby, the amount of pee may have increased with their growth, so the diaper may not be able to absorb the larger amount of urine.
For disposable diapers, the bigger the size, the better the absorbency.
If you can't comfortably fit two fingers under the waistband of the fastened diaper, it's time for a bigger size.
You may need to go up a size if you notice red marks on your baby's tummy or thighs when you remove the diaper.
If the diaper isn't fully covering your baby's bottom, choose a bigger size.
