I have a V5 (Familitchi) tama and was on my first generation. I went to the dating show and married my Violetchi and they only had one child! Any reasons as to why? Thanks.
Normally pure family marriages result with two eggs, but also it might mean that you would have the Space family if you have one baby, with Iwatchi as the baby.
But you would have to have (I think?) married Jewelboxtchi or Sunnytchi.
On my V5, the first generation always has 3 eggs. Then 1 character gets married, and it and its spouse turn into parents. There is one baby. The 2 parents are shown on the happy/hungry button thing (I forgot what it's called...sorry)
