My child was always well behaved. She held our hand when little all the way round, and honestly, never expressed a view that was different to ours when small, clearly.
when older, as said, we have bought and sold several times, she would give an opinion, but never anything demanding, she never felt it was her decision, more she was a welcome part of the process.
the last time we bought, she was 17, and her and my husband did wish one house and me another, but we aligned as a family on the one I wished. Previously we have aligned on one he wished.
even though she’s a young adult now and not living at home, I’d still have her come on viewings, and part of the decision. I value her opinion and ultimately it is still her family home.
when she viewed for her rented flat. She sent me links, videos etc and let me be part of the decision too, even though ultimately it was her decision.
i think if your kids don’t behave, like jump on sofas, touch shit, dirty walls, then you should have the sense not to take them, or if they are going to be demanding and think it’s their decision, then again, have some sense and leave them home. But if you’ve well behaved kids, who enjoy being part of such a major decision, then take them if you wish.
only the parents know what’s right for their family
