Best Health Insurance from my options

My head is spinning a bit trying to figure out the best health insurance strategy for 2025 for me, my wife and our newborn. Me and my wife are approx 40yo and (currently) healthy and barely use our insurance, but I've no idea how much insurance our newborn (will be 2m in Jan 2025) will use (currently no know health issues) or what types of claims. Options are everyone on my plan, or her plan, or each on our own plan and one adds the child. I would really appreciate some opinions if anyone is able to see an obvious best option….

My Plan (Co-Pay, higher premium, lower OOP max)

Deductible (per person) = $500 Deductible (family max) = $1,200 Out of Pocket Max (per person) = $3,000 Out of Pocket Max (family) = $6,000 Copay = $25/$35 Annual Premium (solo) = $1,690 Annual Premium (self+child) = $4,862 Annual Premium (family) = $8,138

Her Plan (Coinsurance, low premium, higher OOP max)

Deductible (per person) = $1,750 Deductible (family max) = $3,500 Out of Pocket Max (per person) = $4,600 Out of Pocket Max (family) = $9,200 Coinsurance = 25% Annual Premium (solo) = $78 (bizarrely low) Annual Premium (self+child) = $1,365 Annual Premium (family) = $2,015

Current guess is that if the child is on my policy he will use his deductible but then the rest of his care will (hopefully) be low co-pays, but if he is on my wife's plan with coinsurance he is likelier to hit his OOP Max. I continue to anticipate (hope) for low usage of the insurance for the two adults.

If I draft that up my extremely bad math and poor assumptions seem to suggest that me taking the child on my policy and my wife sticking solo on hers might come out the cheapest. Am I talking garbage?
