How to start a bottle feed. My baby was rejected every day for 1.5 months. I try two times every day, but no improvement. Please help

Bottle feed- Not as efficiently utilized/absorbed as breast milk.Nutritional content depends on proper preparation (human error).Some babies have difficulty tolerating certain nutrients Breastfeed- Contains high levels of nutrients Easily digested and absorbed Content varies according to the milk production stage, which meets the changing nutrition requirements.
