Mother in law issues

So my mother in law has a good heart. She means really well but I get really annoyed with her fast. She lives in CA, and we are on the East cost. Since my son was born four months ago she only saw him once. My husband decided to fly her out with his autistic brother to stay with us for a whole week( don’t worry they quarantined). I’m not saying he’s autistic for nothing or to be rude, as I work as a counselor for children with autism, but it just makes things harder because he is very loud and messy in an already disorderly house from having a four month old who doesn’t like to sleep (who has already been woken up several times due to his brothers loud voice). Well, his mother is very kind but there’s a language barrier (from Mexico) so they all speak to each other next to me and I have no idea what their saying and they talk about me clearly because I hear my name and “ella” frequently. When I ask what she said my husband brushes it off or says oh nothing she’s just asking questions about the baby. So anyways, she’s been here for almost three days and I have held my son maybe 5 times. I put him down and turn around and he’s gone, she took him upstairs to the guest bedroom where they’re staying. I go to feed him and she goes “I do” and grabs the bottle. I go to change him and she says “ I change” and gets down to change him and grabs the stuff from me. When I say it’s okay, she insists and then I feel bad because I know she’s excited but like I want to do stuff for my child. I went to bath him the other day and my husband goes “ my mom would love to do it herself” and I was like no it’s okay (he knows I have a routine and love our bath times) and he gave me a look and I was like I guess she can help? So I’m sitting there washing him and she goes and grabs ANOTHER cloth and starts washing him. I was like alright.... so I let it happen and then I go to wash his hair and she goes “ oh no!!! In his eyes!” I said it’s tear free he’s fine and she goes “no eyes red” I was like no they aren’t... (wtf) So I ignore and continue, and she takes the cup I use to rinse his head as I went to grab it and does it herself. I said to myself whatever she’s only here for a week I’ll give it to her. And then I go to wrap him in a towel and she takes him from me and brings him to the living room (not where I keep his clothes) and he’s crying, and she goes “ clothes?” I was like yeah I’ll bring him upstairs and went to take him and she says “no I do.” So she proceeded to go up to our room herself and goes through our room to find him clothes. Wicked invasion of privacy if you ask me.. I’m so done at this point but I let it go and say I’m putting him to bed I just need to lotion him and get him dressed, so as I’m lotioning him and doing the massage routine I do for him, she takes the lotion, and pumps out far too much and starts going over his arms and chest after I JUST DID THEM. I’m fuming at this point so I take him uo to bed. So I start Next morning we’re going out for a walk and she tried to take the carrier from me!!! I was like it’s okay he sleeps when I have him on me and she said no I want! Ans tried to tug it from me. I was like next time you can... she said ok, and went and spoke Spanish to my husband probably talking shit. It’s like what the fuck lady!!! During the walk I went to take him out to feed him and she had the back pack on, and proceeded to fill the bottle herself and say she wanted to feed him. I said it’s okay I’ll do it fast and she huffed and walked away. Like is it me?! I get she’s here for a week but there’s a line and a thing called BOUNDARIES. You can hang with him and take pictures and sing to him and HELP, but asking to bath and change and feed and put him to bed and to wear him and take him from me if he’s crying is just too much. I want my child! Is it me? Someone please help me I don’t know what to do. She’s literally taking over. She also refuses to let me do the dishes or my own laundry. Literally won’t let me. I know she wants to help and is excited to be here but I feel she’s making me out to be useless In my own home. Also, he came down this morning smelling like perfume. I looked at my husband and go what’s on him why does he smell like this? And he said what do you mean? I was like there’s something on his face is this lotion??? And he goes “ my mom said his face was dry” ... it was not. She put SCENTED lotion on his face. I look at it and it’s beat red. I took a wipe and wiped it off and he’s like you’re being ridiculous it’s lotion I was like do you not realize they make lotion for children and babies for a reason? Their skin is SENSITIVE, without PERFUMES. She came down and gave me a dirty look and asked him in spinach why I was doing and he explained and even though I can’t understand I could her it in her tone she was being bitchy. Like is it ME.
