Still here and need support

[SH_]

poschan, the thought to give d7 some choice in the matter, sounds good. But I do say be cautious with this approach. It can put a lot of pressure on her to make a big decision and can cause some issues about having to pick one parent over the other. You know your d and her maturity level, but keep that in mind

I strongly encourage that a co parenting plan be set prior and just follow it.
Suggestion as it is the one that my L helped me with as my d will not be away from either parent more than 3 days in a row.
