Many babies will drink from any nipple as long as there are nutrients flowing from it. However, there are some infants who are a bit more refined in their selection of where their formula or milk flows from.
With that said, we advise you to buy the best nipple the market has to offer. According to our research, we have found out that the most ideal choice are the Avent nipples. They come in different flow rates for your baby.
