My little guy will be 4 months on 1/5 and he is close to growing out of Pampers size 2. I have 2 huge boxes (one each) of Huggies and Costco brand from Costco that were gifts. But I noticed that the Huggies size 3 diapers are about the same size but maybe more narrow than the Pampers size 2. We've pretty much only used Pampers (with the exception of a few Honest Co) and I love how soft they are, but Costco doesn't carry Pampers. 🙁
