Diapers: Gerber Cloth Diapers
Gerber cloth diapers can be used with vinyl diaper covers. These diaper covers add an extra bit of protection for wetness but they are not mandatory. Most people find that using Gerber cloth diapers by themselves is enough.
If you think you might not have access to a changing table, using diaper covers is good insurance. Some people do use covers for Gerber cloth diapers, but its really up to the person. I would recommend always having some on hand just in case you are worried about needing extra protection.
The Cost of Gerber Cloth Diapers
Gerber cloth diapers are cheaper than the competition. The same goes for vinyl diaper covers. They can be much cheaper than fancier cloth covers, which is the main reason they are so popular. If you combine the vinyl covers with prefolded Gerber cloth diapers you will save a lot of money over people who use both disposables and fitted cloth diapers.
Giving advice on which diapers to use is a bit difficult, especially if you are pregnant and expecting a baby. All babies act differently. Some may not like vinyl covers, whereas some may have no problem with them. Some may wet a lot and need extra protection, while some others may not go to the bathroom as often. You may have to experiment a bit to see which system works best for you and your child.
