A report's found it's taking too long to identify children with autism or special educational needs in North East Lincolnshire.
It shows more need to be done to diagnose conditions more quickly and families need better support.
It also calls for experts to be brought in to analyse services and help make changes.
Campaigners in Grimsby have previously called for the entire support service for children with mental health issues needs to be overhauled.
Parents claim its difficult to get the right diagnosis and the right support in place.
