Hi deepthi... babies generally tend to roll over after the 3rd month so don't worry 😊

Hi<br> Each baby take their own time to achieve milestones. Give some time. Roll over happens after three months or later. If the baby is active and taking feeds well don't worry about it right now

Yes it's absolutely ok. <br> Baby should gain double weight when he turns six month and triple when he turns one year. <br> Achieving milestone differ from baby to baby. <br> Don't worry<br> Check this link Understanding baby development nd milestone<br> <a href="http://app.babychakra.com/feedpost/51273?ref=ra36738&c=app_share&pid=android_consumer">http://app.babychakra.com/feedpost/51273?ref=ra36738&amp;c=app_share&amp;pid=android_consumer</a>&amp;
