tw for this i’m babysitting my baby brother and hes laying on my lap and keeps trying to put his hand near my crotch and it’s driving me mad

Advice, coping techniques, just distraction needed. Yesterday night, my parents asked me if I could take care of my baby brother and I’ve been wanting to help them out so of course I said yes, and I was taking care of him with my other brother. A big fear of mine that I’ve told my therapist about is that my OCD will latch on to my new baby brother. It hasn’t happened since he has come home with us, but now I feel like something is brewing. My little brother is prone to throwing up so he already got the shirt He was wearing all dirty so I went to my mom‘s room and decided to change his onesie. I called my other brother for help by helping me sit him up while I put the shirt over his head after the shirt went over his head. My other brother was walking out and that’s when I clipped the buttons on the bottom of the onesie and continued to carry him around the house, but it’s that action that my mind is obsessing over. Me clipping the buttons of my baby brother’s onesie. I can’t get over it. My mind keeps replaying that one thing because my thoughts are saying “oh what if you accidentally inappropriately touched him “ and I even went out of my way to avoid touching his diaper because I knew my head would start spinning shit like this. But ever since last night, I can’t stop thinking if I accidentally traumatized my little brother some how. I know I didn’t do anything wrong. I’ve helped my mom change my brother‘s clothes before. My parents literally check his diaper if he soiled himself, but when I do anything that has to do with making sure my brother is clean and healthy my head tries to make me feel sick and crazy. The thoughts are getting worse and getting to the point where my head is trying to make me feel like I’m weird for wanting to change my brother out of his dirty clothes. I’m just so scared that these thoughts are gonna get worse and I’m trying not to freak out right now so I went for a walk outside. But im still getting such intense anxiety. I dont know how to cope or what to do advice coping techniques would be a such a help ive been doing so good with avoiding compulsions. I just need help to ground myself. I dont want to go to my mom with this ill feel worse. Is me writing this a compulsion?

So I was fantasizing about my crush and when I was into my brother pops up or something and it makes me think I was turned on by him like I’m upset about that now

POCD I was holding my nephew, he's a newborn, and he was getting hungry so he started squirming around and grazed my chest (yes I was fully clothed). Of course, that caused anxious groinals.. It didn't feel bad in the moment just very very anxious feelings, and without thinking, I was holding his head still right there and I was moving it closer in that spot (at least felt that way) to make the feeling continue I guess. It felt like an urge because of the groinals. It was such an anxious all over my body feeling. I was so anxious and triggered by that feeling. It's like my groinals were so intense I automatically leaned into them? So I ended up having another groinal. After that I put the baby down and realized what had happened. Did I just hurt my nephew without consciously realizing it till after? Is this OCD?
