Thanks for your query.
First of all i will advise for EXCLUSIVE BREAST FEEDING.
crying of babies is due to many reasons,most important thing you should see that baby is taking feeds normally.is active.
was she having fever
,if not i will not advise crocin
drops.You can give colimax
drops for few days.
keep her in prone position most of the times,but she should not be left unattended.
In case she becomes lethargic,is not accepting proper feeds then i advise you to get pediatric consultation.
Your baby will be fine.
