Girls, hi! They first said it was hypertonus, now they say there's probably a problem with neurology. Sent to see a neurologist. The daughter is restless, sleeps soundly, wakes up every 20 minutes, sometimes sleeps normally. Spits out a lot, more than two tablespoons, I would say 2 cups. Once every 2-3 days she cries like she's howling ( this is the first time I heard a newborn cry like that). And it's not crying but a scream, as if afraid and then cries for 15-20 minutes without stopping, turns purple. Nobody really says anything, maybe someone has encountered such a problem? Weight gains normally. Everywhere it
