Time she was left on her own to do things her own way, IMO. Not unkindly, but just back off and get back to your own life. She may feel overwhelmed. She may feel that she can't get things right! I gave my DiL lots of unsolicited advice on breastfeeding before the birth of DGC1, all with the best of intentions. I was mortified to find out that she was worried that I was disappointed in her because she changed to bottle feeding (I wasn't, it's their baby and their choice) - I had to do a lot of positive affirmation of their parenting to make up for that.
Do you think you know when you are going to die?
Terrible relationship with DIL - am I the problem?
. he also doesn't obey as much as I do, but never did with daughter and her sister either! I do try to do it her way but on occasion gave non-vegan by mistake and did other things wrong. I do not want to lose the ability to see the kids so keep it zipped.
