What are you wearing in the middle of the night?
How old are you?
And how old are your clothes?
Well, the answer to those questions will depend on how old you are.
The average person is about seven months younger than the average baby, but there are a lot of reasons why you might not have your baby’s clothes, shoes or diapers with you for the night.
In the US, for example, the average newborn is about five months older than the typical adult, according to the US Centers for Disease Control and Prevention.
“If you’re a baby and your clothes are still on, they’ll be washed out on the bedsheets and clothesline.
That means that it’s not a great idea to put diapers on in your baby crib or baby stroller for the first few weeks, even if it’s the right size.
The diapers will not get soaked and they’ll just fall out of the baby’s body, so it’ll be too cold and wet for them to stay there,” said Dr Lisa Miller, a clinical nurse specialist at the Child and Family Health Centre, a non-profit health organisation.
Baby and toddler clothes should be washed on a regular basis, so they don’t absorb the chemicals in household cleaners, she said.
“If you have a baby who has a very dirty diaper, you should wash them on a daily basis, just to be safe,” Dr Miller said.
If you do wash your baby, she advised you to use a soft cotton towel to clean them.
“The cotton should not be so soft that it can easily get stuck in the creases and cracks, but soft enough that you can get it off without tearing your baby,” Dr Lisa said.
The baby’s clothing should also be wiped with a soft damp cloth.
To keep your baby warm, your baby can sleep on a soft, warm blanket.
The blanket should be kept clean to prevent it from drying out.
Baby clothes can also be washed and dried overnight by using a soft cloth and a damp washcloth, Dr Miller added.
For older babies, baby clothes should still be washed, dried and laundered on a monthly basis, according a 2014 study by the CDC.
A baby’s shirt or sweater should be wrapped in a wet cloth, and a soft towel or washcloth should be used.
After the clothes are dried and washed, a baby can be put back in them at night if you’re not wearing them.
However, if you do wear your baby clothes, they should be removed and washed with a warm wet washcloth.
