Play tents are lots of fun for children. A baby tent allows them to have a private area of their own, to play in. Ask six-year-old, who probably has five of these to play in, she surely loves them. She definitely rotates out her tents frequently, so that she does not get bored.
They can be used for a play house too for when you are not around. Stakes are needed for a child's bed tent to be strong enough to hold the weight of a kid who will sleep there. Usually, the stakes are made of wood. However, plastic ones can also be used, as long as the kid is not too tall for it to hold him/her in place, and the tent is away from his/her reach. If your kid is very young, you can try an inflatable bed tent instead of the regular wooden one, which are usually more durable.
Some of the Play Tent you can find on the internet, are those which can easily be put together, so that you can assemble it right away. If you want something that can be assembled by yourself, you can try one that will need you to hang sheets and quilts, which are usually where the tent will be hung. It is also available in different sizes. If you will buy a tent like this, it will be useful as a play room too. And if you have a newborn baby, you can also have this as a nursery, where the baby will grow up playing in it before he/she is taken away to the crib.
