I am going away Fri-Mon in a few weeks.
I am a SAHM and before DH goes away he checks that we are alive and that is about it, but before I go away I make sure he has enough of everything he will need, batch cook and bake, write him a list of all the places and times the children need to be somewhere, organise presents id they have parties.
In the back of my head I think that maybe this time I should leave it, and let him sort things out himself, like he does for me. But then I think all that will happen is nothing. The children will eat crap that he can find, the children wont get anywhere (DD has a party and a Rainbows trip and DS1 has a football match). I am not guessing, I know this will happen as he is beyond laid back about stuff like this. The kids like it for a day or so then they realise what they have missed and get grumpy.
I should add that he works away alot, long hours too and we have a DS who is autistic and hates trips to the supermarket etc.
