Hi c&cmom,
I think you are right having the gut feeling that the issues could become bigger and bigger over time. Especially if your dd will get the feeling that she can get her way if she pushes hard enough... .
Being somewhat flexible and willing to listen and negotiate a workable compromise are all very good skills we can model for our kids.
On the other hand, giving in to our kid's pressure is a dangerous signal that our no does not mean no.
So, the key is to know the difference.
When enforcing our boundaries, it works best to be gentle, kind AND firm.
One very important thing is: if we state a boundary, and then give in, we are worse off than if we did not establish the boundary. So, there is a lot of forethought and preparation that is required before we introduce the boundary.
Here is a good video you might find helpful on boundaries by R. Kreger (she also talks about this in her book 'The essential family guide to BPD' it is the
