- Main article: Birthday
If it is the player's birthday, then the player's Mii look-alike will call the player to come to his/her apartment. Following that, many of the residents on the island will sing "Happy Birthday to You" and give birthday cake. The only Miis who will show up are the ones you have pampered the most.

If a married couple has a baby, they will call to announce it. You will get to choose whether it's a boy or a girl or to just go random. You will then see its appearance, which you can change or just go along with whatever is there already. The parents will then tell you the name they were considering for the baby, which then you can choose a random name, create your own, or simply go with what the parents wanted.
After that is done, the parents might call you again to have you help take care of the baby- usually if it will not stop crying. If the baby is young enough you can rock it. If it is older, you can play "Peekaboo" with it or rub its head, chin, or stomach. You can also do this if you're babysitting the baby.
If the baby is grown up, the parents will call to announce. You will then get to choose to keep the child as a permanent resident or send them off as a traveler. You can edit their appearance before they leave, and give them a message to send on. The father will then give the player a family album. If the apartment building is full or there are too many travelers at the port (50 total), the parents will keep the child until next day.
If you have already sent out a traveler Mii that has been away for a while, you might get a letter back from them telling you about their adventures. Whether or not you get to see a picture of them with an islander depends on if the other island they went to allowed them to show it.
If a traveler stops back home, they will hand the player a special food, say a message spread by the other island's owner, and talk about its level. Before it leaves, you can have it eat a snack or take a nap, or say goodbye immediately.
