Like what we always say, no fixed rules for this - whatever you think is suitable given how your child is responding to the lessons, and this will vary from child to child.
Felicity (6.5 now) always demands at least 2 days of lessons each time, and we also do a separate chord recognition exercise for all 9 chords, as well as spend time watching more youtube videos from the Resources section (which you don't have yet in your build).
Just remember - you're the best person to judge what to do. Just trust your instincts! There's no 'getting it wrong'!
