It is possible that your milk is sufficient and babys hunger is satisfied hence not demanding or taking milk from a bottle. To increase your supply you can try to express breast milk after each feed as this will create additional Stimulation. To ensure baby is eating enough keep a track of the number of times the baby passes urine - we expect a minimum of seven adequately wet nappies in a twenty four hour period. A last alternative is to have some one else take over the feeding with a vati and spoon. When the baby sees the mom the natural instinct is to demand for the breast. It is recommended that bottle is not used as it can cause various other problems.
