My LO wakes up every 10- 45 minutes at naps and at night. I'm exhausted and she cries everytime unless I give her boob. Her cry is so loud and piercing I can't even let her cry for more than a few seconds. I can rarely calm her down with just a pat. What can i do? Has anyone experienced this? How long did it last? She's 4 months and 3 days (17 weeks) and this has been going on for almost 2 weeks
