Bring it up. Eating, chewing, moving food with the tounge to the back of the mouth, swallowing, nursing, etc. are all motor skills that prepare children for speech. Having a feeding issue could cause a speech delay, or both issues could be caused by the same issue. Either way, catching it early is best.
If your daughter has an issue that EI agrees to treat, take your daughter to see a private therapist too. EI is there to help your child be functional when she gets to school, they are not there to be everything she needs to maximize her development. Sometimes that happens, but you should not count on it. Find out if she needs more from a private therapist and suppliment what you get for free with private services.
Good luck!
