Where to begin?

Abi has been going through some indications of imminent milestones (e.g., sleeping badly, separation anxiety from me).  Today, while we were together at home, she was unhappy unless I held her – sitting a few feet away from her was not good enough.  I knew that this morning she had just hit a new milestone (sitting up by herself from a supine position) – so I thought I understood  the reason for her particularly clingy behavior – I was wrong.

Here is an unposed picture of what Abi did this evening (note, she did not get any help getting into this position):

Help!
