uh Marta, this is a soft spot for me. I tried to answer to post a couple of times already but I could not find an agreement with myself on what I want.
I hate TV, I grew up watching far too much TV. And I can't avoid to watch to TV if it is switched on. Even if there is no audio or the TV is far away, I just stay there watching TV like I am hypnotized.
DH also do not like TV so we do not have TV at home. Striclty talking, DS does not watch TV at home and I am happy like that. Often I wonder how I was able to find time to watch TV in the evenings when I lived with my parents. Of course DH and I watch movies and TV series using on demand platforms, but we do it rarely more than two days a week.
DS watches TV when he is at my mum's and he likes a lot Masha and the Bear. When he is at DH mum's she puts DVDs for him and she has a huge collection of classic Disney cartoons. I do not particularly like any of those options but I do not want to fight those battles. Indeed it is good that DS can learn that different households have different habits.
My big concerns is youtube videos as DS seems addicted to them. He wants to see them all the time especially when DH is around, as DH is more prone to say yes to him. We started watching simple videos in English (i.e. little baby bum or dave and ava videos), then we added masha and the bear and Thomas the train. But now he wants to see videos of training arriving in train stations (yes, there are people making movies of all kind of trains arriving into remore train stations). To my dismay now he also wants to see videos of people unboxing toy cars.
I know that video and internet is a strong part of my family and how DH and I are. Technically we can say we met each other thanks to the web. And I have no particular reasons to deny him to watch videos sometimes, especially because I check what he is watching and I do not feel particularly dangerous contents in what he likes. Then we comments together what he sees quite often. And also for him is good to listen to a lot of English.
But still I do not like it. I cannot rationalize exaclty what. A possibility is that I fear he will become a nerdy socially incapable teenager that just wants to play computer games. Believe me that too many people I met in my life are on that side and I know what I am talking about, and I do not want this for him. On the other side I am a strong believer that denying too much something is coutnerproductive as DS will develop even more his preferences from what I try to deny from him.
Back in topic, Marta, my experience is that I cannot totally choose what DS watches in TV and he has developed his preferences that do not coincide with mine. So I had to do compromises on that and I would rather not doing that.
To finish with a funny story I say that DS at 2yo is totally capable of selecting videos that he likes from youtube. Once he wanted to watch the advertising of Panda (the car, don't know if you have it) that he selected by himself for at least 5 times one after the other. At least he will never have issues with technology...
