Regardless of a child's race or economic status, all boys wear a collared sweater with brown trousers, and all girls wear a simple belted dress. However, the color of the sweater or dress varies from child to child.
As of the DLC The Elder Scrolls V: Hearthfire, there is an option for the Dragonborn to adopt children and send them to his/her home. The Dragonborn will be able to raise his/her children and have a variety of activities available to them once they have adopted a child. 
Existing NPCs (all Honorhall Orphanage orphans):
Existing NPCs (through parent death/murder and being sent to Honorhall Orphanage)
- Clinton Lylvieve
- Minette Vinius
- Etc. (note, not all children will be available, or it is unknown if the others do become adoptable when orphaned)
New NPCs introduced with Hearthfire DLC:
- "The lake here is so pretty." - At Lakeview Manor.
- "Dragonsreach is so cool! The kids there are mean, though." - If living in Breezehome, Whiterun.
- "I played with Lucia in the park today. I feel sorry for her." - If living in Breezehome, Whiterun and Lucia is not adopted.
Children cannot be killed, injured, or knocked unconscious, nor can they be pickpocketed. Dragon Shouts also do not affect children, no matter which shout is used; however they can still be hit, and the weapons skill can be increased from doing so. This is mainly for cultural reasons as children (such as Helgi in Morthal) do die in Skyrim.
Even though children cannot be harmed, attacking a child will incur assault charges in the same way as harming an adult. If a child sees the Dragonborn breaking the law, he or she will warn the nearest adult.
- Aventus Aretino: Initiates the Dark Brotherhood questline with his task to kill Grelod the Kind.
- Babette: Alchemist assassin in the Dark Brotherhood. Although actually a 310-year-old vampire, she is considered a child because of her physical form.
- Fjotra: The potential Sybil of Dibella in the Temple of Dibella in Markarth.
- Helgi: The deceased daughter of Hroggar who was burned in a fire. She exists as a ghost.
- Nelkir: The illegitimate son of Jarl Balgruuf of Whiterun. Key character in the Daedric Quest The Whispering Door.
- Haming: One of the few survivors from Helgen. With his parents, Torolf and Matlara dead, he now lives with his grandfather Froki Whetted-Blade in Froki's Shack.
- Sometimes when performing spells while in the presence of a male child, he will ask to be made invisible. There is no way to make him invisible, but he can be lied to. He will then run around the town and try to scare people while thinking he is "invisible."
- Although there is no way to make children invisible with the current list of spells without the use of the PC version's console*, the child class has a fully recorded voiced line for being turned invisible for both male and female children, and even scripted conditions enabled to play these lines if turned invisible. The child will exclaim "Hey, I'm see-through!" when turned invisible.
- The console can be used to add an expert level illusion spell Fade Other, which was never actually made playable
- Some children can be given a coin. Sond and Bottar will reveal a map location if given a coin. Svari will also thank the Dragonborn greatly if given a coin.
- Children in Skyrim tend to have similar inventories. Some items they tend to carry are: Quill, Charcoal, Roll of Paper, Broken Sword (Braith), Inkwell, Shoes, Child's Clothes, Gold Coin, Iron Dagger (Males), Drum, Lute, Flute, Wooden Ladle, various Ingots (Blacksmith Apprentices, generally), Leather Strips, Apple, Bucket, Leather, Sweetroll, Long Taffy Treat, Honey Nut Treat, Boiled Creme Treat, and empty Wine Bottles. There are most likely many others; these just appear to be the most common.
- If attacked enough, a child (any of them), will draw an iron dagger. If attacked continually, they may even start attacking the Dragonborn.
- All children has the same face and skin tone, regardless of gender and race.
- Invisibility spells do not work on player-adopted children, they will always be able to interact with the Dragonborn when he/she comes home regardless of his/her invisibility. Exiting conversation however, will cause them to lose sight of the Dragonborn.
- When standing on top of furniture (i.e. a bed), nearby children will humorously remark "I'm not allowed to stand on furniture..."
- Some children may hire mercenaries or The Dark Brotherhood to kill the Dragonborn if they catch him/her committing a crime. This was intended to be done by adults only.
- When items are dropped near children, they may tell the player that they dropped something and attempt to give it back. No items are added to the inventory, however.
- Doing a charged Werewolf attack can sling back children like any other character; however, they will be unharmed as they get up.
- Sometimes when using a Frenzy spell near a child, they will get the effect, and a quite humorous scene follows, as every guard in the city tries to kill the child, eventually chasing them out of town. It is possible that the child may actually attack the guards, and kill them all, as children are invincible.
- After downloading Hearthfire all children will have their clothes unequipped (sometimes Skyrim updating for newest version can fix this error).
- Occasionally, a child will go to use a Cooking Pot, Alchemy Lab, or an Enchanting Table. When a child does do this, the player may notice the model stretches to the adult model, and shrinks back down afterwards.
