Speech therapist: Catherine Barry on GiliGums Mushroom Teether “I really like this teether because it encourages the safe mouthing of objects, which is an important developmental skill. Important oro-motor skills like side-to-side tongue movement and the development of the strength and precision of the oral structures involved in clear speech is encouraged by the use of this teether. This is also a good alternative to dummy use (which can negatively impact oro-motor development as well as the development of clear speech), while retaining the soothing and calming benefits.”
