How frequently should the nipple of the feeding bottle be changed. The bottle is used regularly 4-5 times a day.

A. Then you should change the bottle only if you are using the bottle 4 to 5 times in a day and you should discard the bottle after 1 to 2 months itself because the more we use a bottle the bottle also needs to be discarded like nipple so you can just change the bottle after a month or so because as a child it going to the growth of the intake of milk and also going to increase even need a bigger bottle over the period of discard the bottle and get a new bottle every two months
