Time will tell but promising.
My daughter was born with a rare syndrome, with multiple defects I including the palate and nasal areas. Breathing at night has been a challenge her entire life, and Cpap/bipap machines just aren’t tolerated.
She is improving daily with the use of bottle, though I wouldn’t say her problems are eliminated. I’m sure it will take longer to build the muscle and tongue position that with a typical mouth breather.
I’m thankful to have a tool to begin helping her with.
