Controversial Cornwall councillor Collin Brewer, who said disabled children "should be put down" has compared the cost of supporting a disabled child with that of public toilets.
Mr Brewer gave an interview with Disability News Service (DNS) where he repeatedly raised concerns about the "burden" of disabled children and said "there may be a case" for killing some disabled babies.
The Wadebridge councillor was re-elected to Cornwall Council last week despite being forced to stand down after causing widespread public outrage over his comments made to a disability support group.
In the interview DNS asked him if there was much difference in euthanasia of a child or a lamb, he said: "I think the cost has got to be evaluated. It is not something I would like to do but there is only so much in the bucket.
"If you are talking about giving services to the community or services to the individual, the balance has got to be struck."
He said: "It [the lamb] would be put down, smashed against the wall and be dealt with."
And asked if a child with a similar impairment should be killed after birth, he said: "That would be up to the decision of whoever is there at the birth."
Mr Brewer was also asked whether there might be good argument for killing a disabled child with high support needs, because it would free up more resources for the wider community, he said: "I am not making that judgment. There may be a case. I haven't a clue how much they cost."
He also compared the cost of funding disabled children's care and support, at a time when mainstream services including toilets, leisure centres and coastal paths, were at risk from the government's cutbacks.
He compared the £250,000 that it would cost to keep 10 public toilets open with similar sums paid out to support just one disabled person.
Mr Brewer, who is currently on sick leave from his council duties because of long-term health, was meant to meet with Parent Carer Council, who held a protest last week at County Hall, and Disability Cornwall but failed to turn up.
