Feedback from mothers using a "cross-cut" teat indicated its use for problem feeders, particularly "windy" or "colicky" babies. The manufacturer commissioned a trial to see whether this observation was clinically valid. A randomised controlled trial comparing the cross-cut teat with a standard single-hole teat was designed. Both teats were identical in construction apart from the feed hole at the tip of the teat. A standard teat pierced with one hole is usually sold as slow, medium or fast flow rate, depending on the size of the hole. The cross-cut has two slits in the form of a cross opening in response to the baby's sucking. The stronger the suck the wider the cross opens, thus making the flow rate of the teat controlled by the baby. There is therefore no need to change to a teat with a faster flow rate as the baby grows.
Babies fed with the cross-cut teat cried less and spent more time awake and content than babies fed with the standard teat.
使用“十字切口”奶嘴的母亲反馈表明，这种奶嘴适用于喂养有问题的婴儿，尤其是“爱胀气”或“患腹绞痛”的婴儿。制造商委托进行了一项试验，以确定这一观察结果在临床上是否有效。设计了一项随机对照试验，将十字切口奶嘴与标准单孔奶嘴进行比较。除了奶嘴尖端的进料孔外，两种奶嘴在结构上完全相同。一个标准的单孔奶嘴通常根据孔的大小以慢、中、快流速出售。十字切口奶嘴有两条呈十字形的狭缝，会根据婴儿的吸吮而张开。吸吮越强，十字张开得越宽，从而使奶嘴的流速由婴儿控制。因此，随着婴儿长大，无需更换为流速更快的奶嘴。
使用十字切口奶嘴喂养的婴儿比使用标准奶嘴喂养的婴儿哭得更少，醒着且满足的时间更长。
