This will depend on the climate where the children will be sleeping. You should match the location with the bag's temperature rating, the child's metabolism, the bag's weight, etc.
Sleeping Bags don't actually provide the heat, it is when our body heats us and he bag insulates (keeps) the heat in the bag. That is why we can get constant heat from the bag.
That depends on the sleeping bag itself. Any sleeping bag that is made for camping in un-harsh conditions would not keep you warm enough in mountain areas.
Because you have more layers on. MOR ROCKS
You could make your baby sleep in a sleeping bag. These bags are very comfortable for the babies to sleep in. they will be adequately warm in it and you can carry them in that. However, you should get it from a good brand.
Some good brands of sleeping bags are Coleman, Eddie Bauer, L.L. Bean, and The North Face. Coleman makes a "double sleeping bag" which would be good to share with your partner, however it is said to be heavier than two L.L. Bean sleeping bags together! Eddie Bauer makes quality products, but can be a little pricey. L.L. Bean lines their bags with flannel to ensure the user stays warm throughout the night. The North Face's Cats Meow is an award winning sleeping bag that is rated for temperatures as low as 20 degrees Fahrenheit and is said to keep its warmth even when wet.
Astronauts in space rockets typically sleep in designated sleeping quarters that are usually small, private sleep pods or sleeping bags attached to a wall. These sleeping areas are specially designed with restraints to keep astronauts in place during sleep in the microgravity environment of space.
Yes, they can, because in space there is no gravity, so to keep out of equipment they have sleeping bags on the walls and on the ceiling.
There are several things to consider when selecting a sleeping bag to be used for backpacking. Weight, insulation, temperature rating, and style of the sleeping back are important elements to be considered. A lightweight sleeping bag is the backpacker’s obvious choice. The savvy camper does not need to sacrifice comfort for weight. Many of today’s sleeping bags are made from lightweight fabric and filling. Comfort and roominess no longer need to be sacrificed in order to have a lightweight sleeping bag. The two most commonly used insulation materials are polyester and down. Down, naturally, provides the greatest insulation, but is not a good choice to be used in wet or damp areas. Down tends to lose its effectiveness when wet. Because of its quick drying time, synthetic filling is the preferred option when camping in areas prone to dampness. Generally, sleeping bags filled with down are more expensive than those filled with synthetic material. When selecting a sleeping bag, the backpacker must consider the temperature rating of the bag. Most sleeping bags carry an EN rating. The EN, or “European Norm rating will list the lowest temperature at which the backpacker will be comfortable. For example, bags with a 40 degree EN rating will keep most sleepers warm if the temperature does not fall below 40 degrees. Backpackers need to be vigilant when checking weather forecasts. Daytime and nighttime temperatures may vary greatly. When unsure of the temperature, select a sleeping bag for colder conditions. A sleeping bag that does not provide adequate warmth is not only uncomfortable, but can be dangerous. For an extra measure of protection, many backpackers choose a mummy-style sleeping bag. These bags are more form-fitting than traditional square sleeping bags. This mummy shape affords more insulation and warmth than other bags. Gathered around the head and face, these bags promote heat retention. When given the option, select a bag that includes a hood. This feature will prevent heat loss through the head. Consider whether the backpacker is right or left handed. Many sleeping bag manufacturers offer models with zippers on either side. The right sleeping bag can be the key to an enjoyable backpacking experience.
Since there is no gravity to hold astronauts in their beds they have to sleep in zipped up sleeping bags that are strapped to the inside of the space station, space shuttle or whatever they are in.
The mummy bags where just your face shows. Keep out the bugs, snakes & scorpions & are very warm.
I suppose that is up to you. But the clothes will likely make sleeping uncomfortable. They will get wrinkled too.
Yes, there are sleep sacks to keep your child covered and safe.
