Dear lactnetters, A technique of "jackknifing" a baby to wake it up is probably "old school". Basically, the baby is bent in the middle, bringing its head down to its knees. However, I have either read somewhere, or perhaps it was at a seminar that we were cautioned not to do this. It makes sense to me that this could be potentially harmful. (increased intra abdominal pressure, or increased inter cranial pressure, or increased thoraxic pressure) Does anyone remember the caution. I am interested in it as someone is suggesting this as an effective way to stimulate a sleepy baby who is not breastfeeding effectively. Thanks, Kathy Bodden
