You probably don’t have a cute milestone card for this moment but it’s a big one! Baby’s first nappy 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 nappies?’ and ‘How big are size 2 nappies?’ 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 nappies 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 nappies you need, you can expect your little one will go through approximately 8 nappies per day. For more information on all things nappy sizing, age and quantity, have a look at our Ultimate Nappy Size & Fit Guide.

Kit & Kin size 2 nappies come in our adorable mouse and panda designs. With baby’s eyes now able to follow moving objects, incorporating our animals into your changing routine is a fun way of interacting at this age.
