Relating well in Grandparenting

I have wanted to keep a journal of my grangparenting journey but was just too dead beat tired to do so. As of current, I have 3 grand children, 3.5 years old, 2 years old and a 6-month old. There was an extended period when my children and grandchildren were staying with us, under 1 roof. It was for practical reason during this covid pandemic when only 5 unique visitors were allowed each day per household. It was also a blessing that I can spend maximum time with my grandchildren. Yet, I'm also aware of potential conflicts if relationships are not handled properly.
