my 6 months daughter rolls over, moves and cries in sleep almost every 2 hours whole night. once I take her close and feed she will just feed for a minute and sleep peacefully. this has been from 20 days and keeping me awake whole night. but this happens only at night. morning once I put her in her cloth swing she sleep peacefully even 3-4 hours in one stretch. Shud I check with doctor or it's normal? Shud I do something
