Because every baby grows differently and at different 'speeds,' our subscription does not automatically increase sizing based on your baby's age. With that said, our subscription is really flexible, you can login at any time to change your diaper size, push out the date out of your next delivery date, change your shipping address, etc. Additionally, if you sign up for SMS notifications you can make edits to your subscription via text.
You can also email us or call us and we are happy to make changes to your subscription for you.
