we have newly bear twin and this avent set be a nice addition to the Avent gift set we already have . you have a nice selection of bottle and the nipple seem to be easy for the baby to use . one thing to not be that this product be not make in China like many other bottle . I want to point that out as some people like to know that info . this be a nice starter set but you will need to buy additional bottle just to have enough on hand . we have the gift set in addition to this and we still need a few more bottle due to have twin . it be nice not to have to wash and\/or sterilize all the time by have more on hand . while it be hard to tell how much the bottle prevent colic they do seem very nice and the nipple seem perfect for we newborn .
