Three days ago, my daughter started crying suddenly, barely calming her down for 10-15 minutes. Then she took a breast and fell asleep. Yesterday was the same. I check her tummy when she cries like that - soft. During the day she's calm, eats, plays, sleeps well. Only at 9:00 PM - 10:00 PM she starts crying when we're getting ready to sleep. Could it be colic? Has anyone experienced this? Share your experience.
