I had an emergency c-section and it's a requirement that there be a paediatrician present in case the baby needs one. We also had to have a 6 week check up with the same paediatrician as a follow up which is standard. I think you can see a GP instead of a MHCN, but honestly the MHCNs see so many more babies that I feel perfectly happy trusting them. If I ever feel uncomfortable though I wouldn't hesitate to get reassurance from my GP.
