This post is based on the assumption that the change in Ishwari character is real and not a false alarm like last time( it doesn't make sense for makers to continue their story in a loop)
i would mention a few incidents before pre-leap
1)Sona convincing Neha to wear the bridal dress which Ishwari also vouched for but was unable to convince Neha.
2) Sona trying to initiate a talk between neha and ranveer so they can solve their issues and avoid termination of their relationship because of financial problems
3) Sona's protest against Ria-Ayan relation and also because of a very solid reason.
4) Sona's impact on Dev's life , how positively he changed and how much her void affected him during both the breakups
after leap there is literally no change in Sona's character apart from her clothing, financial status and most importantly now she is a mother as well. her other qualities are same as preleap
So my question is ishwari is able to accept sona after she clears her role in theft fiasco and save her from falling in her son's eyes but why was not able to accept sona when she did good for her own children even including dev?
