It really has been like going in circles trying to put the CPS visit into sequential context.
Here's a quote, for example, which direly states a request by CPS to perform a welfare check was what prompted the investigative activity at MF's residence.
"According to NBC News, Cy-Fair Volunteer Fire Department public information officer Lt. Daniel Arizpe confirmed a 1-month-old infant was found safe at the home just before 11 p.m., but the child’s identity has not been released.
Arizpe said a call from Child Protective Services for a welfare check at the address prompted the investigative activity. The child, who was transported to a local hospital, had no obvious injuries, the network reported." Snipped from KIRO article @:

However, when you click on the NBC source link within the KIRO article, there is no such statement by officer Arizpe included.
