SimGuruGraham has confirmed that the 7th Stuff Pack for The Sims 4 (which is currently being referred to as a Kids-Themed Stuff Pack) will be released some time in June. As The Sims 4 Dine Out will release on June 7th, we can expect this Stuff Pack to be released sometime in the last 2 weeks of June.
Graham also confirmed that after the Stuff Pack 7 Release, we should expect a new Teaser of upcoming packs, just like we did in April!
