Hi all. I am blessed with my second baby. He is 1 month old. My daughter advika was born in 2016. And he is born on 18/6/21. I just wanna know what is the good oil to massage so that his bones strengthen. Today my mom saying to him that babu ubr one month old you should straighten your leg means khade hote time pairo pe wajan lo. I am worried . Is he weak? Pls guide?
