Reincarnation/ Rebirth/ Transported to another world

I got up to chapter 50 in the novel. Let me tell you the protagonist is one evil bitch there's nothing redeeming about her besides her appearance to be honest. I don't have a problem with it though lol

This girl because a stepmother at a young age I think she returns to when she is 16? And her kids are close in age to her the oldest is 14 I think. It's a pretty good read she's a good mom

I think this is just a one shot shot but Im not sure. The poor girl just keeps reincarnating
