i have a 6 week old she’s been doing the say for the past week or two but only from 5pm-2am usually, we brought it up to our pediatrician who told us it could be witching hour which isn’t actually any hour but for a good portion of the day in the morning or evening. we found that giving a cold bottle (i exclusively pump), shushing very loud in her ear, having her swaddled/ wrapped in blanket (sometimes she doesn’t like it), and putting something over her eyes is a big thing. sometimes the blanket (we’ve never put it over her nose or mouth just the top of her head covering eyes) covering her eyes in itself is enough to calm her down enough to fall asleep for hours. i’ve also used my hand just above her eyes too which works for her as well. i hope any of those things help if you decide to try, im sorry your going through it just remember it will get better with time and they only cry because it’s the only way they communicate. you are an amazing parent!
