Residents in the Muirhouse area of Edinburgh have been working together to raise funds for a memorial to pay tribute to three-year-old Mikaeel.
Now his grandparents Harjinder and Bangarpet have expressed their gratitude to people who helped search for him and left condolences outside his home.
And they have also revealed they wish to donate to the memorial set up in Mikaeel's name.
In a card to the Tenants and Residents in Muirhouse (TRIM), they said: "We would like to express our heartfelt gratitude for the help and support we have received from the community in Edinburgh and especially TRIM.
"In particular we would like to thank the parishioners of St Andrews Church, Edinburgh for their efforts, support, thoughts and prayers during this difficult time. Our family would also like to express our appreciation to those who have initiated the memorial fund for Mikaeel, especially TRIM, Deacon Helen Fisher and the community of North Edinburgh.
"Our family would like to donate towards the Mikaeel Kular Memorial Fund."
Mikaeel's body was found in Fife after he went missing.
