From everything that I can find online, it is a positive thing to show affection in front of your kids. It models affection to your children, and it makes them feel more secure https://www.whattoexpect.com/news/first-year/how-much-pda-okay-front-baby-kids/

My own experience agrees with what I have read. I don't think I ever even saw my father and mother kiss until I was well into my late teens. They never showed any affection, never held hands. Of course, the problem was bigger than just their relationship. Once we grew too old to walk on our own, my siblings and I were never hugged or kissed. It wasn't that they were neglectful; all our needs were taken care of, my mother made sure we ate healthy, we never lacked for all the practical necessities. But affection was never expressed.

It affected us all to varying degrees. I understand from an intellectual perspective that hugging and kissing is healthy, but I am not comfortable with it. My daughter is a hugger, and it took her nearly ten years to train me to hug her. My son, who is more standoffish, gets hugged by his father when he needs it but the few times that I have hugged him it feels so weird and wrong to me, because my instincts were so messed up, that I just can't bring myself to do it often. I try, but it feels so awkward that he senses it and now that he's a teenager it's a little too late to change those patterns.

I wish that my parents had hugged each other, and us, a lot more. Please show your children that there is nothing shameful about showing affection to those you love.

我對母親的見解記憶猶新。她看著自己的一位daughter婦在地板上伸出來，而六歲的她正坐在她旁邊，玩著頭髮，依sn著。我媽媽非常難過。冒犯了他們，好像在做可恥的事情。當我問她為什麼打擾她時，她對我的問題感到困惑。我意識到這是她內心深處的一種情感，以至於她甚至無法說出其來源。然後我想到她自己的父母也完全不相愛（在我認識他們的所有時間裡，他們都一直睡在分開的床上，而且他們的大部分互動都涉及互相na和批評）。對她而言，對我而言，這樣的事情不對。幾乎可恥。

孩子從父母那裡學到的東西，會傳給自己的孩子。幾代人過去使我無法讓自己對孩子產生感情？一個有著很多天生智慧的小女孩打破了我的生活週期。

儘管我不知道有任何關於該主題的研究，但我相信這是肯定的。孩子們從周圍的成年人那裡學習如何成為成年人，所以看看真正的浪漫關係是一件好事。

兩個警告：

1. 如果他們在玩遊戲時照搬你，會怎樣？

2. 如果他們感到不舒服，那就停下來。

其他答案給出了很好的觀點，我只想補充一個重要事實：

孩子們會在媒體中及其周圍看到很多成人行為

孩子們會受到很多關於行為的投入。最重要的人通常是父母。但是他們有時還會在電視，互聯網上看到事物，與其他孩子交談，或者只是在公共場合看到成年人的行為。所有這一切將形成他們對如何表達情感以及成年人應如何表現行為的看法和想法。回答中提到“如果他們在遊戲時模仿您，會發生什麼？這應該使您清楚地知道在哪裡劃界。” -這個年齡段的大多數孩子都會嘗試很多不適當的東西。他們在電視上看過東西，或聽到其他孩子談論他們認為成年人在毯子下做什麼，他們會嘗試的東西。而且，您也不能通過不親切地親吻他們來阻止這種情況。

我認為，對孩子的行為產生積極影響的最好方法是對他們希望看到的所有行為表現出積極的態度/經常在現代社會中遇到孩子。他們會看到許多形式的感情，因此您也應該在他們面前與伴侶保持親熱，並確保他們將情感與自願，積極的行為聯繫在一起，而不會感到羞恥。
