For infants I would recommend using Pampers Swaddlers, which many hospitals use.
They are a bit more expensive, but well worth it.
If you need a cheaper diaper for your infant, Parents Choice diapers or even Luvs diapers are also great.
Amazon Mamma Bear Diapers and Coterie diapers are also good for infants.
Although I mainly used Pampers Swaddlers on my kids when they were infants and they worked really well.
As they got older I switched to Luvs to save money and the Luvs diapers also held up really good as they grew.
