Elizabeth,
Sometimes babies position their tongues on their palates to stabilize the
airway.  Does this baby extend her head to breathe?  Does she coordinate
breathing with her suck and swallow?
You might want to try having mom lean way back while she breastfeeds so the
baby is almost prone.  This can help airway stability and reduce the gulping,
while giving gravitational assistance to tongue extension.  Make sure baby
approaches the breast tongue first, with her head very slightly extended.
Often the football hold works well combined with the above interventions.
        If none of this works, baby should have some suck rehab or see an
Occupational therapist, IMHO.
