My 4 months old baby has recently started refusing formula bottle feed. Since day 1 after hospital discharge she was having a night feed of Formula daily which gradually increased from 30 ml to 120ml till now. Recently since 1 week she is not at all taking bottle feed only wants breast milk. Breast milk is not sufficing her hunger n also it gets difficult for me to move out leaving her with any other family member to take care for sometime. There is not illness at all just the want for breast milk often is what I observed. Please suggest how can I make baby happily take formula as I will be resuming work in couple of months.
