Baby girl is 9 weeks old, but since having her 2 month shots she will start screaming crying around 8-9pm every night. We’ve tried putting her to sleep before that, but she will still wake up crying at that time. I’m not sure if it’s colic or something else? I know colic and the rule of threes but it usually doesn’t last more than 30 minutes-hour, but we have a hard time calming her down and when we do, she usually starts crying again within a couple minutes. Is this normal or something more serious?
