Anyone's baby have colic? How did you know and how did you deal with it? We thought it was a sleeping arrangement/having days and nights mixed up but we've been making a routine and she cries and gets fussy every night around the same time for hours. She sleeps fine during the day in he rock n play which is what we put her in at night. She's EBF but she is a gassy baby. Could it be gas build up at night? We've been using gripe water at night time feeding for a week and no difference.
