my baby boy is 4 months 27 days old but still not yet rolling.... should I get him checked by Dr

A. Hi mommy Its normal and common Some baby roll over by age of 5-6 month If baby’s weight gain and other milestones are okay there is nothing to worry about it Give massage your baby regularly with Babyhug massage oil to make baby’s muscles stronger Also do tummy time regularly it also helps baby to make muscle stronger
