It doesn't hurt to get an eval. It's free through EI.
Daniel is receiving services for a gross motor delay (he's 18 months and has a 6 month delay), and he's getting services for his speech as well. His speech delay isn't as bad, and is rapidly improving - his speech issues are mostly because he's got low muscle tone, including in his mouth, so making some sounds is harder for him.
Our ped wants kids to say 3 words by 18 months. He's pretty laid back
But you might as well get an eval. It's worth the peace of mind if she's not delayed, and if she is, it's best to catch it early.
