Then it is very simple. Add your spouse in immediate family members (or else can mention in dependents but not accompanying, it would slightly delay your current application processing but is way faster than doing a spousal sponsorship later, but you may choose the later in case your husband doesn't want to make his current employer suspicious or otherwise). Further, add your child as dependent accompanying you and add your husband's notarized and explicit consent for allowing processing of your child's PR application.
All the best!
