Milagros,
Patrick used to arch his neck back because he had sleep apnea. He was trying to open his airway so he could breathe better. After his tonsils & adenoids were removed, this problem went away. Patrick was a very noisy breather since birth. Does your baby have this problem?
Patrick's adenoids didn't "look" large. I was insistent that Patrick's T & A be removed. The dr. said Patrick would have to have a sleep study before he would remove them. After only 30 minutes of the sleep study before Patrick was even asleep, the tech said, "Patrick would be having some kind of surgery."
I hope you will see an ENT to see if this is a possibility.
