Our S4's birth day is in August and I am not planning on going to her party so that she doesn't get any ideas about us being a family. Don't know if I am doing it right
Hard stuff! How will you explain to a 4 yr old why daddy won't be at his BD party? Can you give him a separate party that would include your side of the family, neighborhood kids, etc?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
