You probably don’t have a cute milestone card for this moment but it’s a big one! Baby’s first diaper size up! You might now have had some early smiles (or is that just air?!) and baby will be growing a little more active each day. If you still have lots of questions regarding sizing, you are not alone! ‘When to start using size 2 diapers?’ and ‘How big are size 2 diapers?’ are only two of the things parents at this stage tend to ask us. 

So let’s clear this up once and for all! How long do size 2 diapers last? As a rough guide, most babies fit into size 2 between the ages of 2 and 6 months, with some progressing into size 3 as early as 3 months old. In terms of how many size 2 diapers you need, you can expect your little one will go through approximately 8 diapers per day. For more information on all things diaper sizing, age and quantity, have a look at our Ultimate Diaper Size & Fit Guide.
