Unfortunately, you're in a spot where you have to decide how much money you have to hire private counsel and force a nonparental custody action under RCW 26.10 (alleging each parent to be unsuitable to assume custody) versus calling in an abuse allegation to DSHS and having them become involved in investigation of the same. In the former, you, as petitioner, would be seeking custody, but there's a financial price to be paid via hiring counsel. In the latter, you may instigate an investigation, but there's no guarantee that DSHS will remove the child from the mother's care and/or place that child with you. Added to this is the fact that once DSHS gets involved, it doesn't separate itself so easily from a case. Any custodian would be under court order to comply with DSHS, and the goal in its involvement is usually the eventual reunification of child and parent.
