Help me, please! My 6.5 year old has started having a ton of accidents again, #1 only (at night, at school, etc.)

We are about to make a cross country move, and DH moved 3 months ago, so he's been gone. I assume it has something to do with dealing with that. When I ask her about it, she says she forgets to go or doesn't realize she needs to.

I've considered making an appt with her pediatrician. Do you think that is warranted? I'm sick of the laundry and my whole house smelling like pee, plus I want to make sure she's okay emotionally and physically, of course.
