Prioritizing Habits/More than one at a time?

I have just started reading LDTR and LDTR4C to use with our family and I am having a hard time prioritizing the habits to get started.  I know obedience and attention are foundational, and we will be working on those first, but we have big issued with some other habits that I’m wondering if we could do them concurrently with foundational ones.

For example, cleanliness is a huge issue for my 7yo son, focus/concentration on one thing at a time is a big one for my 9yo daughter, and kindness & respect for other people is hard for my 9yo HFA son and my 7yo daughter.

I keep thinking that as we work on some of the foundational habits, others will naturally fall into place.  But then I look at my list and think I can’t possibly wait over 3 months to work on cleanliness!

Help! 😳
