Child health nurse: That small fontanelle will need to get checked out, I think they usually do an ultrasound. Talk to your GP about it.
GP: Yes, we can organise an ultrasound, no worries. Here’s a referral.
Radiologist at hospital: An ultrasound is pointless, we won’t learn anything from it, we’re not going to do it. Talk to a paediatrician.
So now I need to find a paediatrician.
