Travel diapers come in sizes from newborn up to around size 6.
It's a good idea to keep a small pack of travel diapers in your glove box or in the car in case you run out.
However you can and should also bring along a package or box of diapers when traveling for your baby to ensure you have enough diapers.
The diaper size that babies stay in the longest are size 3 diapers.
Then the next size would be a size 4 diaper which is what most babies wear until they are potty trained.
A newborn goes through around 10 diapers per day so you would need at least 300 size newborn diapers for 30 days.
A baby when first born goes through around 3,650 diapers in a year.
As the baby gets older they use less diapers and then most often babies go through around 1,850 to 2,000 diapers a year.
A toddler uses around 8,000 to 10,000 diapers until they are potty trained.
The amount of diapers that your toddler will use before they are potty trained depends on when they are potty trained.
The longer your toddler stays in diapers the more diapers they use until they are potty trained which can be as much as 8,760 diapers if they are potty trained by age 4.
Assuming your toddler uses 6 diapers a day and then you multiply that by 365 days that would mean that the toddler would use 2,190 diapers in a year.
If your toddler uses 4 diapers per day then it would mean that they use 1,460 diapers per year.
The amount of size 6 diapers you need depends on the age of your child wearing the size 6 diapers and how often they pee or poop.
Most kids who wear a size 6 diaper will need between 3 to 4 size 6 diapers a day, although some kids may use 5 to 6 size 6 diapers a day.

Most kids will potty train before they need a size 6 diaper or size 7 diaper but some kids may need the size 6 diaper or size 7 diaper if they are not potty trained until age 4 or 5 years old or if they need diapers for bed wetting or incontinence.

As a general rule of thumb, babies tend to stay in size 3 diapers for the longest period of time which is about six months by some estimates.
Assuming six or seven diaper changes per day, this could mean you might need anywhere between 1,000 to 12,000 size-3 diapers before moving on to size 4 diapers.
If the diaper fits too loose then the kid needs a smaller size diaper and if the diaper is leaving red marks around the legs or waist then they need a larger size diaper.
