They don't usually fit the typical newborn very well. We started using them around 10 pounds and have been using them since and plan to continue to use them until she PLs. Some people prefer sized dipes though because they tend to be less bulky but I don't have a problem with the bulk. Works fine for us and saves $$$ IMO.

No formatter is installed for the format bbhtml
It can also depend on the brand. We have some BBH OS that DS is about to outgrow the rise on. And OS can make it hard to fit the legs of skinnier babies sometimes.
