gearing up for this weekend

My ex-husband has agreed to take the kids this weekend so that I can go to the DAN conferences. My kids have not spent a night away from me in four years, they have just been spending Saturdays with him. I think that they will be alright but I still worry. My son is still on one medication and my daughter still takes one to help her sleep, and then they both take vitamins and she takes allergy medication, and he takes probiotics in the morning. It is a lot to remember and he is not used to doing any of it. I know that the kids are smart and they know how I do things. they have also gotten better at turning down foods they know they are not supposed to have. I am planning on packing their food and their dad is going to buy some stuff. ever since he broke up with his girlfriend he has been doing better for his children and he has gotten along with me better. He is following the diet plans better and he calls to check with me before he feeds them anything new. I have never packed for them for more than a couple of hours so I am just packing everything, they are probably taking 3 bags each for two days.
