The playpen has a number of excellent uses. Normally they are used by parents as somewhere to put your child when you cannot supervise them for example you may need to go to the door because a guest has arrived but do not want to leave your baby on their own, at times like this they are perfect because you can just put you infant in there while you leave the room for a short time.
Some parents use them as a place to put their child in the day time when they need a break maybe there are visitors coming and you do not want your baby to get over exited.
Another good way of using the playpen as a sleeping area would be when the house is becoming a bit much for the child allowing them a break from all the noise and stress. For more information about baby craddle you can search best pack n play reviews online.
It is important to get the playpen all set up like a bed before you use it like one, if it is uncomfortable for them then it is unlikely they will fall asleep like you want them to.
If you are still looking around for the playpen that works for you but cannot find it then you may want to look for a specialist there are a few out there that provide playpens with both a bed and a changing area a bit like an all in one result.
