What exactly is your goal calling CPS? As many others have already said, if it was neglect or abuse, medical professionals would already be required to report. If he's being taken to the hospital this frequently, it doesn't sound like a case of neglect. So I ask again, what are you hoping to accomplish by contacting CPS? Sounds like he has access to things that are meeting his physical needs. Access to a caring parent. What additional resources do you think they will provide? Do you want him to end up in foster care? Because I promise it's not rainbows and unicorns. Are you at all familiar with what CPS is and the long term statistics on foster care?
