AIBU to feel MIL treats my son like a toy

[Eri2020]

As a bit of background I don't have the best relationship with my MIL, is not bad but is hard. We don't speak the same lenguage (I'm learning it and can barely speak it) and she can be really pushy, I spent like a month alone with her and in that time she try to teach me how she would like me to write, dress, eat and try to tell a hair dresser how she would like my hair done instead of what I wanted, etc.
So now that DH and I have a son (13 months and her only grandchild) I'm a bit apprehensive towards her. What drives me crazy the most is that to me she treats him like he is a doll for her amusement, she forces his hand so he would play with his toys the way she wants him to play with them, to high five her or clap, if he doesn't comply she doesn't let her play with the toy (I've seen her when she thinks I'm not looking) or she forces him unto a bike cause she likes to see him on it even though he can get on and off from it by himself. I've told her with my limited lenguage skills to stop forcing him but she doesn't seem to understand or pretends not to. Would I be unreasonable to make a bigger deal of it and ask DH to have a serious conversation with her? Or is this just how some grandparents are? My parents are nothing like that.
I'm not even sure if that is bad for my sons development as he doesn't seem to enjoy it but he does loves his grandma.
Sorry is a bit long

With a language barrier that is difficult. Can your DH not say something to her? In her own language so that there are no misunderstandings?

dh needs to talk to her, i take it he agrees with you on these matters.

He does agree that she can be pushy but when I mentioned that I don't like her forcing his hand he said that maybe she doesn't know any other way to play with a baby, as if it is not a big deal, but this is probably cause for him our son is the first contact ever that he has with a baby so he doesn't know any better eather (he doesn't treat him like that) . I'm sure if I ask him to talk to her he will but I'm not sure if I'm exaggerating for pressing the matter as is not the first time I complain about her

I think removing your child with a very firm ‘No!’ would be sufficient. I’d be doing it every time. Does she live with you?

It doesn't sound great, but I think at 13 months, it won't be very long before he stops letting her treat him like that. If you don't love together and you are nearby to intervene with things you see I would probably just leave it for now, given the language barrier.

Learn the word for Stop, then you get a chance to move over to her and move your child away each time she trys this. That and no each time she tries again.

Use google translate to tell her in her language

@mrsbyers, I would stay away from Google translate, you have no idea what could be said to her !

OP, feel awful for you, does by any chance your DH know his mothers langauge? I feel that she does not respect you, but she will probably respect your DH.
With the way she is treating you and your son, I would no way on earth let her see him until she has had a stern talking to, it even sounds like she is putting your DS in dangerous situations, so this HAS to stop. Also, I'm assuming she is never left alone with your son, God knows what would happen,
also, can I have some more details about different languages ect?

Yea, I stay away from Google translate as I have sound rude before my mistake. So my husband and in laws speak Czech, my mother tongue is Spanish and we speak English in between the two of us so his lenguage would be the third one I'm learning. I do know how to tell her in simple terms don't do this I don't like it but she pretends she doesn't understand me when she doesn't agree so I would have to have DH to tell her, is really annoying really.
And you are right we made the agreement sense we notice she doesn't respect our boundaries that she is not allowed alone with him as she only follows them when she thinks we are watching.
We are temporarily staying with my in laws while we get around buying a house but got delayed with the pandemic, fortunately is a big family house and they live on the second floor and we on the first floor completely independent but she comes by every day to play with him.

And thank you all for the advise I would definitely try the saying No and removing my son approach, specifically sense I already told her I don't like it. I think that would be harder for her "not to understand".
