If you want to bottle feed your baby it should be introduced at 40th day of birth. Also, you can try now too but it will take a little time. Use feeding bottle instead of normal bottle
Try the one from Chicco or Philips avent

You can continue bm till one year along with foods...

Hi is your baby teething or having cold and cough?

Hi can you send image of it?

Hi you need to start first with sips from sipper or Katori then gradually cup or glass

You can try glass or spoon. If you can express your milk and mix it with normal milk so that he can develop taste. In fact, since he is older than 12 months of age you can also add very small amounts of sugar to develop the taste

But personally, do not add too much amount of sugar

Hi apply neem paste on nipple of bottle and offer when baby is hungry and also take milk in Katori and spoon and give when baby is hungry

Try to reduce the quantity n gradually replace the milk with water so he may associate that with bottles. After 1 year bottle is bad for oral hygiene n may lead to tooth decay.

Keep trying during sleep hours ... keep trying all I can say....
