Here's some more ideas - and I'm loving how the book is going. It's a comforting book.
* Jax being an emotional roller coaster - one moment, happy, the next moment worried, the next, irritated etc. Caine tries, and fails, to help. Jax throughout it, calls him Mama rather than Caine, being stressed. Maybe this one's another slow-burn, that style is nice.
* Again, Jax chewing on just about anything and everything. He refuses to accept anything meant for it, and Kinger and Caine ask him about it, try to gently stop him, but Jax only talks to Kinger, who seems to understand much better than Caine does (ironically, since he's teeth)
*Caine trying to take them on an adventure that suits little kids, but Pomni still doesn't like it at all and clings to Kinger.
