Did you know that unlike when giving baby bottles of formula milk, you never increase the size of the bottle teat for bottles of breastmilk.
The bottles for breastfed babies always stay on the smallest teat size.
This is to prevent nipple confusion and to make sure the baby does not become accustomed to the faster flow of the bottle, compared to the flow of the breast.
Also be sure to use the "Paced Bottle Feeding" method when giving a bottle to a breastfed baby, as it mimics the flow of the breast.
You can stop doing Paced Bottle Feeding once baby starts holding her own bottle and thus controls the flow herself.
