Babies in Tomodachi Life are completely random acts of accidents. As long as a couple is married and are in good terms with each other, you’ll eventually have a baby… eventually.
*Make sure you have babies enabled in the town hall! Its in the Town Hall, Options, Baby Settings, Toggle On
You can check the relationship status by pressing the L or R button in your Mii’s apartment.
Once the baby is born, you can actually choose the gender for the baby, or let chance decide. Then you can have the parents suggest a name or offer your own name. You can also change the way the baby looks! At such a young age. But because the baby is so young, you can’t really tell how s/he will look until s/he’s much older. You will be given another option to change the name, the way s/he looks and personality features.
So a few days after getting married in Tomodachi Life, my Mii told me that she was thinking about having a baby. I was completely alright with that.Within the week, she gave birth to a beautiful baby girl!
She asked me about how she looks and I thought it was too funny to say “Hmm?” to whether or not her daughter was cute.
