A mini crib is a space saving crib that works well for newborn babies through until around 18 months to 2 years of age. Parents like them because they take up less room in their homes and do the same job as a standard size crib.

Some mini cribs have features or extension sets that allow you to convert them into toddler beds or seats once your baby has outgrown the crib itself. This is worth looking into so you can get the most out of your purchase. It is recommended that you buy any extension kits when you buy the crib first time round to avoid the set you need being discontinued or remodelled.
