Dylan Cecil's family have released this statement:
We would like to thank everyone for their help and support during this difficult time.
We would like to express our gratitude for all the messages of sympathy and support from both the local community and wider public across the nation.
In particular we would like to thank the people involved in the search – the police, RNLI, HM Coast Guard and the Burnham-on-Sea Area Rescue Boat (BARB).
We are still extremely traumatised but very grateful that it appears Dylan has been returned to allow us to bury our son.
The relatives of Dylan Cecil, who slipped into the sea from a jetty, say they are grateful after police believe they have found his body.
The mother of Dylan Cecil says is "devastated" but will stay in Burnham-on-Sea for "as long as it takes" until her son is found.
The search for a four-year-old boy - who went missing in the sea while on holiday - has been called off by rescuers.
