HI all, Thanks for the explanation of SNS vs. lactaid. I haven't used the latter, so am not as familiar with it as I should be, however, I haven't had any problem with the SNS as long as the tube is looped so that it doesn't drip out by gravity. I use the same principle when I am using a syringe/feeding tube device (without the plunger), and find the babies have to suckle quite effectively before anything happens. I can also decrease the amt of flow with the SNS by hooking up the second tubing, or increase flow by unhooking it to get an extra airhole. I appreciate your comments... Jan B.
