Bassinets and changing-table inserts can be useful. Just remember that you should never leave your child unattended within those devices in a play yard—no matter what type (or feature) you are using. Your infant may be content to sleep in her bassinet insert, but she's safest sleeping in a full-sized crib. That's because your child may begin moving around and could fall out of the bassinet, either onto the floor, or to the floor of the play yard, causing injury. You'll also need to remove the bassinet or changing station, (or flip the changing station to the outside of the yard, depending on the model) when your baby is in the main part of the play yard to avoid the possibility of the child getting trapped under those attachments.
Once babies pass the one year mark they are considered toddlers and most kids that age aren't ready for a big kid bed. That is when the BabyBjorn crib makes sense because it is a little bit bigger than most standard pack 'n plays giving your tall baby or toddler room to sleep safely. This model weighs only 11 pounds making it great for travel and has a modern, sleek design which looks great with any decor if it is used as a permanent bed. It can be used with children from newborn up to three years of age.
