This makes me wonder if after feeding they are less sensitive to pain till they finish digesting? IDK. Just one of the silly things I think about in these situations.
Here is the complete thought here.
1. Issue with teeth hurt so she is going nuts.
2. Eats and food coma sets in and is less sensitive to the tooth pain.
3. Pain comes back and rampage begins again.
4. Gets fed again because of pushing and food coma provides temporary relief.
All speculation but it might carry some weight. I would add checking teeth or other painful health issues to check when pushing begins.
Best wishes with her.
