Recently, the Centers for Disease Control and Prevention and the American Academy of Pediatrics revised developmental milestones, aiming to make it easier for parents, caregivers, and healthcare providers to spot certain conditions more accurately. 

See an article on milestones and red flags of speech and language development published in Digital Journal by Andrzej Lewandowski Speech Therapist Polskojęzyczny Logopeda w Chicago:

Absolutely not. You can self-refer to a speech-language pathologist, which means you don't need a doctor's referral to book an appointment. However, check to see whether your insurance company requires a doctor's referral.

Words cannot describe how satisfied my family and I am with the Speech Therapy services my son has received from Andrzej Lewandowski. Andrzej is very knowledgeable in his field and it definitely shows in his ability to diagnose and in coming up with different strategies to help his specific diagnoses and needs. Andrzej is very kind, patient, and personable and is amazing at keeping my son engaged by centering therapy around play and across various platforms. My son's speech has progressed tremendously since starting Speech Therapy and continues to do so daily. I know my son would not have come this far if it wasn't for the help and guidance of Andrzej.

Andrzej Lewandowski is a phenomenal bilingual Polish speech language pathologist who performs speech therapy services in the greater Chicagoland area. He specializes in the treatment of pediatric speech and language delays and disorders and is exceptional at performing speech and language evaluations and assessments. He provides speech therapy for children with articulation and phonological disorders as well as expressive and receptive problems at their own homes. I highly recommend Andrzej as a pediatric speech language pathologist to help children with all of their communication needs.
