Yeh, I can't add anything more to what Joseph said. My kids know where I work and they've been to my office. I always let them know the plan and where they will be and where I will be. They know they can message me or call me whenever they want to. Just making sure they know I am available - I am very lucky to have a flexible workplace that I can up and leave if i need to and make up my hours later.
I haven't done any family type activities on the regular right now because things with W are all over the map. But, all our interactions in front of the kids are chill and positive. Any time we needed to talk about serious stuff, we always do it after kids go to bed.
I know kids will be fine. They will adjust. The fact that they have to still $ucks because it's so emotional for them too.
