See women planning trips with kids. occasionally — one's down with them (3,7)
I believe the answer is:
Here is my best explanation:
'kids occasionally one's down with them' is the definition.
I can't judge whether this definition defines the answer.
'see women planning trips' is the subsidiary indication.
'see' becomes 'lo' (archaic word meaning 'look!').
'women' becomes 'w'.
'planning trips' becomes 'spirits' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' is the link.
(Other definitions for low spirits that I've seen before include "Depression" and "Mild depression".)
