I recall my babies having some stinky heads, sometimes quite strong. I attributed it to nursing lying down which had their heads quite near my armpit. I'm not making light of things. I just hope it is something that simple for this mother's and baby's sake. Allison Laverty Montag BA, IBCLC, RLC Wisconsin, USA Well, it's pretty complex, but excess ammonia comes from impaired methylation and enhanced breakdown of methylation cycle intermediates, especially BH4. I would be curious if the baby is exhibiting other indications of increased histamine sensitivity, such as flushing, hives, diarrhea, rashes or eczema. Jennifer Tow, IBCLC, USA & France Intuitive Parenting Network, LLC Good morning all, On a Facebook page someone asked about her infant's ammonia-smelling sweat on his head. A whole list of answers, of course, and many addressed the ammonia-smelling sweat in some people who do heavy workouts, insufficient hydratin and probabe lack of carbohydrates. Some mused that, while baby seemed to be getting enough hydration (lots of wet nappies etc) he might be sweating the odou of his moderately dehydrated mom. I think this is a long shot, but is it? Anyone any idea's, research, physics explanation? Wondering in southern Netherlands.
