What’s considered “normal” in infant feeding: A discussion with Katlyn McGrattan.

Is it ever “normal” for infants to cough during feeding?

Does it make a difference whether they’re breastfed or bottle-fed?

What should med SLPs actually understand and implement when it comes to infant feeding?

Infant feeding and our role as med SLPs is one of my FAVORITE topics to discuss, and my heart practically did a break dance when I got to sit down with Katlyn McGrattan, PhD, CCC-SLP, to discuss THIS very topic!

Katlyn is an SLP and a researcher at the University of Minnesota. She lives, eats, and breathes the world of pediatric feeding and swallowing (seriously, as a hobby, she and her husband are developing a medical device to better diagnose infant feeding goals).

Tune in to this week’s episode of the Swallow Your Pride Podcast where Katlyn discusses research on infant feeding and swallowing disorders, the importance of understanding the physics behind milk flow, and what med SLPs should understand when it comes to working in this corner of our field!
