DLA Guilt/Indecision

I keep going back & forth on it, have downloaded forms & guides etc. My son is undiagnosed, unlikely to be assessed for a few years yet. He starts mainstream school in Sep but doesn't seem that much more work than any other kids his age.

I also thought we may be better waiting until he's in school as its so close to hols & more support services will be involved then. Autism outreach, specialist salt, inclusion support & hopefully ehcp.

Would we be better waiting? We're not desperate for money and I doubt he'll get it. It'd be nice to save for him just in case tho.
