Under 16s/Children
We would like to advise that we are unable to accept registrations for any accompanying people (including spouses and children) at ECE 2023. This is due to health and safety considerations, the Pharmaceutical Code of Practice around the promotion of products to non-Health Care Professionals, and restrictions in-room capacities due to Covid-19. For registered delegates who are parents with small infants and babes in arms, there will be a breastfeeding room available close to the main registration area. Please ask the staff at the Registration Desk to show you where this is. There are no childcare facilities onsite at the Congress, therefore childcare should be arranged separately in Istanbul. To comply with insurance and safety requirements, infants must always be held or be in a pushchair. Entry to the breastfeeding room is subject to all regular ECE 2023 Congress entry regulations.

Babies are permitted to enter the Congress venue with their parent/carer to travel to and from the breastfeeding room only. Please note that children and spouses are not permitted in any ECE 2023 session halls, exhibition areas or adjoining spaces.
We thank you for your understanding.
