It's not for overnight. It leaks.

I don't use these overnight because they aren't absorbent enough, but they are a good daytime diaper. However, I find with using coupons, I can buy pampers or huggies for less money. Don't be fooled in to thinking that Costco always has the best prices.

Since this was our first we had no idea what brand to buy so we tried a lot. A lot! This was the one we've been using for the majority of the time. They never leak and the price is fantastic. We tried a few other brands that were comparable in price or cheaper and they leaked. These are very reliable, even overnight!

These diapers are great! The only downside to them is they do get a bit damp on the outside of the diaper after awhile, even if it is not full. But it is soft and comfy for baby, stays on well, and effectively holds in messes.

I really liked these diapers, until the tabs starting ripping off all the time. I took it back to Costco and got a full refund.

I find these diapers come at a great price and work very well. However you need to change the diapers more often to avoid leakage. I change my daughters diaper often but at night time she likes to sleep and if I don't change her during the night she will be soaking wet by the time she wakes up the next day.
