I had csec as well, started malish from 12th day. We used figaro olive oil for malish but would suggest to use cold pressed coconut oil

Hey vedika....have you visited your Gynaecologist yet?She will be the best person for you to tell when to start your maalish as for baby, you can start off with cold pressed oils or coconut oil (organic).Use cold pressed coconut oil for stretch marks or bio oil.Moreover stretch marks are basically genetics related.

For baby massage use coconut oil or any good brand baby massage oil like sebamed, mamaearth..for stretch marks use biooil, palmers, mamaearth..also you can have your massage now..avoid the stitches area..and do the massage of your baby yourself with soft hands..Avery lightly
