Yes I've had a problem with it since I was a little kid. And yeah I know something needs to be done but my aunt and uncle act like its no big deal!! Either that or they are just tired of arguing with him about it. He tries to hug me quite a few times a day and he is always touching my arms, rubbing my shoulders, pulling my hair or whatever. And I mean several times each day. Ugh...!
Did you have a problem with him hugging on you and such when you weren't pregnant? It really is hard for someone mentally challenged to get it, if they ever do, and it can be really upsetting to them if they DO get it. How often does he try hugging you? If it's not much I'd honestly just brush it off.. but if he's to the point where he's stinking every night, something more needs to be done about his hygiene in general, even if he IS screaming about it, it's unhealthy, especially since he is your brother, and he is the uncle of your baby, he's going to be around at least once in a while and your little one needs to be around clean hygienic hands!
I have tried explaining to her that its the hygiene but she doesn't get it and the nightly shower is hard enough, he is very defiant and has behavioral issues on a daily basis. And I feel bad repeatedly saying "can you please not do that, I don't really like to be touched," my whole family looks at me like I'm an *******. :(
Making a mentally challenged person understand something is very hard sometimes, but you just have to keep repeating your self in a nice way and he will get it sooner or later but it may take some time. For your aunt just explain to her about the hygiene and maybe she might even make him shower more if you point in out to her. You just have to be sweet and gental I hope it works out for you
