Did I cross a boundary?

I have OCD and I’m struggling with something that just happened. My nk (18months) is going through the worst sleep regression. Yesterday nor me or his mom could get him down for a nap. Today he was down much easier but I was still so wary about waking him up. I had changed his diaper before when I thought I got a whiff of something.

I was trying really hard not to flip him over or do an unnecessary change bc once he’s up he won’t be able to go back down. He was sleeping on his tummy so I tried to smell again but couldn’t so I stuck my hand in his diaper near his backside to check for poo. I went as far as my middle finger and the interaction lasted three to four seconds. I didn’t feel anything but I got nervous again so I put the blanket over and tried to feel his bottom again over the blanket and again felt nothing.

I was looking at the nannit camera and realized it caught it on camera and I’m scared it looks bad. You can hear me asking both times in a whisper did you poop? And the footage starts with my fingers in his diaper before pulling out and putting my hand in his diaper to see if I could feel more. I already told the mom I had to put my hand in his diaper to see if he pooped but I’m scared she’s gonna think it was something different. I went through bad stuff as a kid so I never wanna make a kid feel uncomfy nor do I want people to assume I did something bad. I also never do diaper checks like that. I try to peek through the backside or feel through the leg hole but this wasn’t possible with position he was in.
