H.T.
The only other things I might suggest is to hold her in a closed bathroom while the hot water creates steam (about 10 minutes or as long as you can stand, then suction out her nose as soon as you leave the bathroom. The steam helps loosen up the congestion so you can more effectively suction it out. Also warm compresses (not hot) on her face or chest, back (warm damp washclothes work fine). Other than that, just try to keep fluids in her and comfort her when she needs it, and wait for it to pass. It seems as if you are doing almost all you can. If it doesnt improve in a couple weeks, see doc in case she develops ear or sinus infections. I hope she feels better soon!
