My son has the lip callus, receding chin, flat philtrum, his tongue bowls when he screams / cries,
his outer upper incisors have worn away and he has had so many issues with eating solids (to the point of becoming anemic), he has been constantly congested with ear - infections since he was about 6 months.
Teeth — 42 in number — 20
upper and 22 lower — are strongly developed and meet in a scissors bite in which part of the inner surface of the
upper incisors meet and engage part of the
outer surface of the lower
incisors.
