Flat head severe? Normal? Help

Shaunna

Sorry I need to vent and I’m looking for advice. I have been doing EVERYTHING from tummy time to turning head on sides when sleeping and my baby’s flat head is not getting any better. I even bought positional pillows with a hole in the center. Does this get better with time? Is this a severe flat head? Pediatrician is not doing ANYTHING and said they don’t recommend helmets anymore. Opinions?
