What is bottle rejection?
Bottle rejection is when babies refuse to latch on a baby bottle after being breastfed. There could be many reasons behind your little one’s resolute bottle strike.


First, it’s the TASTE. 
Baby formula tastes different from breast milk. Different brand may have different tastes. Sensitive babies can get really picky with the taste of the formula. Try to switch to another brand when you think it’s about the taste.

Second, it’s the SHAPE. Baby bottle nipples are, again, shaped very different from mother’s breast. In order to drink breast milk, a baby has to open his or her mouth wide to use about 40 facial muscles at the same time. Bottle teats, however, do not require as much effort. Nipple confusion can be reduced by selecting a bottle that has a wide teat similar to mother’s nipple.

Third, it’s the FLOW SPEED. It is very important to keep the record of your feeding time and taking the average for future reference. The average feeding time for a baby is about half an hour when they are being breastfed. The conventional baby bottles have relatively wider holes in the teats, so the babies drinks milk at a rapid speed. In the mother’s perspective, reducing the feeding time could mean more ‘extra free time!’ If the baby is constantly fed with the fast flow, there’s risk of infant obesity and lagged facial muscle development.

Fourth, it’s the TEMPERATURE. The temperature of the formula or breast milk has to be around 36.5 degrees Celsius (97.7 degrees Fahrenheit) which is human body temparature.
