If your spouse and child are present in the U.S. on valid H4 status, you can file I-485s for them at any time before your case is adjudicated. As long as their H4 visas remain valid and they remain eligible to enter as H4 dependents, they should not have a problem reentering the U.S. while an I-485 is pending. If they will not be eligible for H4 status at the time of their travels or upon return, they should obtain advance parole before traveling abroad.
