Charlie Gard campaigners have been urged to show consideration to the parents of other children being treated at Great Ormond Street Hospital.
The High Court judge in Charlie’s case warned there were “lots and lots” of other sick children at the hospital.
It follows complaints from the family members of other children being treated at the hospital.
Mr Justice Francis said the relatives of those children may not want to be confronted by campaigners.
A spokeswoman for Great Ormond Street acknowledged the hospital had received complaints from families but would not provide further details.
Mr Justice Francis was speaking while overseeing the latest hearing in the 11-month-old’s case in the Family Division of the High Court.
Charlie suffers from a rare genetic condition and has brain damage.
Lawyers for the hospital said on Friday a new scan of Charlie made for “sad reading”.
Earlier this month the judge condemned people who had abused and threatened Great Ormond Street medics on social media as a result of Charlie’s case.

Specialists at Great Ormond Street say the therapy will not help and that life support treatment should stop.
