"Completely ordinary clothes. It's better than being naked, at least."

If the player changes the Mii's favorite color, the clothing will change accordingly.

Baby clothes are special types of clothing in Tomodachi Life that are only worn by babies. The baby goes through six different clothing changes for each day as they grow up. The personality of the baby determines the clothing's main color.
A newborn baby will wear a special outfit that is only seen during the moment they were born. It is a white bonnet and is wrapped in a light yellow blanket.
After a baby's birth, they will wear cuddling clothes (otherwise known as nursing clothes in EU regions). This is a light colored onesie with polkadots and diaper.
On day 2, the baby will learn to crawl, and is dressed in crawling clothes to match. This is a solid colored onesie a little darker than the last one, with a matching bib featuring a duck for yellow, a train for blue, a car for light green, a robin for red, a fish for cyan, an orange for orange, some grapes for purple and a heart for pink.
On day 3, the baby will learn to stand up and wear bouncing clothes. This is a white shirt and light colored underwear, with a matching bib.
On day 4, the baby, now a toddler, will learn to walk and wear first-steps clothes. This is a darker colored shirt and red underwear.
On day 5, the small child will wear boys'/girls' toddling clothes. These clothes are unique and are the only ones that differ depending on the gender. Boys will wear a white t-shirt with colored stripes and orange shorts, while girls will wear a colored gingham dress.
On the day the small child has grown up, they will wear a larger version of the boys'/girls' toddling clothes during the announcement. Upon choosing whether to move them into an apartment or travel the world, their clothes will change.
If the player chooses to have the Mii be a permanent resident, the Mii changes into either a hoodie and shorts (boy) or tunic and leggings (girl).
If the player chooses to send the child off, they will change into a traveler's uniform, consisted of a long-sleeved buttoned shirt, boots, a green neckerchief, a pair of goggles, and backpack. The bottom of their uniform depends on gender: a male child will wear blue shorts while a female child will wear a red skirt. The shirt, goggles, and backpack trim get gradually darker when their ranking goes up.
Once a child grows up, the player will get a chance to change their personality. If they end up in a different category than before, the child's clothes color will change accordingly, including in the baby album. However, if the player lets the child stay, their default clothes won't change if the player edits their personality after this.
If a child is grown up and the player lets them stay, and the player changes their appearance, the Mii's appearance in the baby album will not reflect the new change.
When a child is born, their favorite color will always be red despite their clothing color based on its personality.
Miis will never change back into their regular clothes after they get new ones; however, the player still can change them back.
