Why do you keep burbing ??

According to reading material, babies on breastfeeding had a lower occurrence of burbling compared to bottle feeding. However, Carissa burbs after every breastfeeding meal, it does not go away even though you may had been patting her back for a long time. A case or wrong technique ?

Sometimes while patting, the air does comes out, but within 30 mins of lying in her bed she starts burbling again. This is affecting her sleep especially at night.

The solution so far we found is to bottle feed her warm water or breastfeed her again.
Yesterday's poo had a sour smell... overfeeding ?? Well gonna wait for tomorrow's poo to find out more.

God bless..
