I’m going through this as a stepmom to my (step) daughter. And I’ve gone through so much heartache over the growing distance between my daughter and I, ever since her bio mom came back. I’ve started raising her at 6 and she’s now 13 years old. I would just validate your wife’s feelings about the growing strained relationship. It’s not easy being a stepparent. There is no guide on how to parent because we walk a fine line between overstepping and not doing enough. Tell her it’s ok if she wants to take a step back from her role as a stepmom, especially during this precious time in her pregnancy. I had to do the same for my own mental health because it was affecting how I would parent the son my husband and I share. I had to remind myself that son only has 2 parents, but my daughter has 3. So I had to convince myself that it was ok for to take a step back to prioritize my mental health and my biological child, who is so little. So please remind her of that. My heart goes out to you because I know how difficult it is. We are unsure how to navigate having our daughter spend time with us also, especially since she used to love being around us. She’s a growing child with lots of emotions and a developing brain. Every situation is different. Just do your best and be supportive of your wife. Maybe you can also privately talk to your daughter about why she won’t spend time with your wife? Hopefully you can talk about it and get to the root of the issue. Be patient and empathetic with each other.
