The supplied evidence cannot answer whether non-forceful bottle offering affects infant cortisol or stress β no controlled trial, cortisol measurement, or caregiver-context study is present. The only relevant data point is that feeding refusal appears in ~19.7% of jaundiced neonates as an illness signal, weak evidence and inapplicable to your infant, who feeds normally at daycare .
What is missing: studies measuring salivary cortisol during pressured vs. non-pressured bottle feeding; trials of caregiver identity (primary vs. non-primary) on acceptance; any data on advanced neurodevelopment and feeding selectivity. Home offers by a non-primary caregiver without forcing remain an inference, not substantiated fact.
