Query: Liked them before but they started to leak

We've been using huggies for the past year and really liked them, until the last 2 shipments. For some reason the diapers leak on the sides, as if the elastic was loose, but the diapers are on securely. We haven't changed the way we put on the diapers, and I noticed that the diapers we have now seem thinner and also the elastic is not as tight as ones from previous boxes we got. Will definitely be trying another brand after we finish this box.
