With the going outside thing, if she only stands on the porch cash she be trusted just to do that and not go any further, sometimes I think there is logic what they ignore, e.g. the dangers you mention are off the porch so in her logic the porch is fine ???
No. Our snake issue in the warm weather also extends to the porch. I wish she could just go outside whenever she pleases, but it just isn't safe here.

She has scheduled activities on all but two days a week. Some are only for 1/2 hr, others are 3 hours. I try and keep her busy at home with a mix of helping me with household tasks, jobs that she can do (placemats on the table, making bed, etc), play time both with me and DD2 and on her own and then just downtime of watching a movie or something.

I guess I'm just hoping something will click. I want her to have her time away from me at home. If she wants to be on her own, chilling out in her room, I don't want her to feel like I'm breathing down her neck but while she keeps doing things like this, I need to constantly have eyes on her.
