Mayor de Blasio’s wife is shunning her own pet project, the pricey and unproven, taxpayer-paid ThriveNYC, to launch yet another broad-outreach publicly funded mental health program.

Chirlane McCray, a presumed Brooklyn borough president candidate, mugged for the cameras while holding a baby at the launch of the $43 million “New Family Home Visits” program that is notably separate from her embattled $1 billion ThriveNYC mental health plan.

The program will send health care providers to the homes of every first-time parent in the city to help them with anxiety and depression, infant feeding and referrals to services like food stamps.

The visits will start this year in Brooklyn and expand in 2024 throughout the five boroughs after the mayor leaves office in 2022.

DJ Jaffe, executive director of Mental Illness Policy Org., said the universal nature of the program doesn’t make sense. “Rather than providing home visits to every single family having their first baby, the services would be better targeted to first-time parents who need help. The ‘something for everyone’ approach adopted by Mayor de Blasio will result in high numbers of families that don’t need help receiving it, and large numbers of families that do need help, not receiving enough of it,” Jaffe predicted.

McCray told The New York Times that the visits are not a part of ThriveNYC and will include “clearer measuring sticks” such as a drop in emergency room visits or cognitive development.

Critics have said ThriveNYC lacks metrics for determining success and doesn’t do enough to help people with serious mental illness.

“Not every mental health initiative is part of Thrive,” McCray spokeswoman Jaclyn Rothenberg told The Post.

ThriveNYC already spends $3.2 million a year on similar post-natal programs that provide public awareness about communicating with infants and mental health screenings for homeless moms.

“Our new program is for all first-time parents in the city and services will be tailored to their needs,” another McCray spokeswoman said.

Councilman Robert Holden (D-Queens) was skeptical that the home visits would have better results than ThriveNYC. “I’m always wary of new programs and new spending from this administration,” said Holden.

“The Mayor and first lady seem to come up with new incarnations of old programs all the time, and it’s difficult to measure the outcomes. Given the track record of ThriveNYC, I’m not so sure this will help new parents as much as the administration wants to claim. As The Who wrote, ‘I pray we won’t get fooled again,'” he said.

But Jaffe said he’s happy the home visits aren’t under the ThriveNYC umbrella.

“I am glad to see that this program, as well as the recently re-announced Mental Health Corps are not being incorporated within Chirlane’s ThriveNYC, since that program has been thoroughly mismanaged,” Jaffe said.

Earlier this month, the city merged the Mental Health Service Corps with the public hospital system and slashed its budget following claims of mismanagement. It is still a part of ThriveNYC.
