First of all, don't lose hope and don't give up.
It takes 4-6 weeks to establish breastfeeding.
Always Offer breast before bottle every feeding.
Reposition and switch breast for every unsuccessful latch.
Try pinching you're nipples when attempting to make him latch.
Keep trying even if he cries (it's going to be frustrating so be patient).
Offer bottled milk for a second then immediately offer your breast again.
Last resort lang dapat ang bottle.
Be patient. Once he got used to your breast he won't latch back to bottle.
