Parents: help me parenting while separated (2)

[Ripe]

Question:
My kids spent last night with me.
What do you tell you S7 when he starts saying after being called to attention: "The other house is much better than this one, it has chocolate mousse prepared by mom, it has XXX and YYYY! And this one has not!"?

Ripe, kids say things like this in innocence, he doesn't mean it to be hurtful. He's just pointing out that Mom has mousse! So just say "wow, mousse sounds yummy!" and, like Jpeg suggested, find something your house can be known for. A special recipe, a craft, an activity, something. And I'll be he goes and tells mom, "the other house is much better than this one because we get to play indoor Frisbee!"

I think it is more than just that, SunnyB.
Yesterday I had the kids with me.
S7, after entering the flat, saw on the wall some of his new drawings that I had put there (STBXW took with her the dozens of drawings the kids had done, emptying the walls). He immediately became angry and took them out, saying he would take them with him to the new house.
He also repeated several times that he did not want any longer to come to this house, this was his last time, that he would always stay with mom, etc, etc.
Finaly, he took another piece of paper and drew a sun, some clouds, an airplane and three central figures, identifying them by name: brother, mom, me.
Under the ground, to the left of the drawing, he drew another figure in horizontal position, two Xs as eyes, which he identified: dad.
He gave me the drawing.
I told he was being mean on purpose, that he was hurting me and he knew it.
I prepared dinner.
After dinner I read the kids the usual bedtime story. By then he was OK.
I told him that during the weekend we would talk about his feelings and mine (obviously, he said "no!"). But we will.
