Thanks to AmiAmi we have the release schedule for Limited/Regular edition KIDDY GiRL-AND DVDs:
Animate provides the schedule for the Blu-rays:
Rather surprisingly they are releasing the DVDs two volumes a month so by the time the first Blu-ray volume is released in March the DVDs will be up to episode 10, and the final volume also comes out three months later.
