Hi bottle feeding is easy so baby might stop taking feed from you. So keep latching the baby to your breast often.

Try to divert his attention may be it help talk to him give him some walk

Also its not important that baby is crying due to hunger always he may b feeling colic or want to play or feeling bored

Hope u r burping him well

He may have peed in between thats y he feels hungry his stomach is so small that it fills and empty’s. If he is peeing 12-15 times a day that means he is getting enough of your milk. Also some children like to have niplle in their mouth to sleep may b that is the reason he cries
