The Royal Society of Medicine hosts monthly study days that are open to anyone interested in paediatrics. They are aimed at ST4-ST5 level trainees, however anyone is welcome. Paediatric trainees only pay £45 for the day (which includes lunch if you book in advance).
The next in the calendar (not featured below!) is Paediatric Gastroenterology on 14th March.
You can find full details of upcoming study days, including programmes, here: Paediatric RSM Days
