Triplets! How do you do raise them!??

I also only once got triplets, I was so surprised! But well, challenge accepted. I gave them fussy, independent and inquisitive trait, and it was fun to play. I didn't give them high chair and hired butler (that family is wealthy) to take care after garden and wash dishes. They got level 3 of all their skills before aging up. I always took them out to park or to visit siblings. That way, I enjoyed playing.
