It will happen! It takes time, and it is important to not stress out about it and stay positive. Keep focusing on recall and awareness. It does work. 
ADA = All Day Awareness. It is a form of waking meditation. Here is the tutorial post.
I don’t have kids, but my other half does shift work so I have a constantly changing wake up time. Initially, the mantra ‘When I wake up, I will remember my dreams.’ helped me. At any point that I wake up during the night, I attempt to lie still and question what I was just doing to try and recall my dreams. Any fragments I then note down before going back to sleep. Of course, sometimes I’m lazy and fall back to sleep anyway…
