Luvs! We have used them for DD since she was 2 months old (they don't come in preemie and she needed them until then) and have NEVER had an issue.
Now our DS is using them as well. We used the pack of Huggies the hospital sent us home with and then switched to Luvs.
If you have a Target near you watch for their sales... sometimes they have the big cases on sale for $16.99 and if you buy 2 you get a $10 Target gift card to use on anything. So they really come out to $11.99 a case, awesome deal!
