B.S.
After 21 years as a child care provider, I wouldn't give up my crib tent for anything. I use the Graco Pack and Play port-a-cribs for my youngsters that range in age from newborn to approximately 18 months, depending on size and weight. I have ONE crib with a tent on it. It has been a life saver. I seem to wind up with one *adventurer* from time to time and the crib tent has been my only means of keeping him/her safe. It was about the same price as another crib, itself; but I was able to install it myself and have had no problems with it. Mine has lasted at least 10 years and is still in great shape. It was a very good investment.
Infants stay in the same area with me until their naps are sometimes disrupted by the older childrens' activities. Then they are moved to a separate room set up with the port-a-cribs for their two naps a day. This room is monitored.
Around 18 months to 2 years, I move my kiddos to sleeping bags with pillows located in the area where we do our activities, for naptime. At this age, they need only one nap a day right after lunch. They understand requests and gentle reprimands. They are ready for big beds and understand about staying put until naptime is over.
They are so much fun at every stage of development!
Good luck and God bless!
