OCD toddler?

A lot of toddlers are like that with getting dirty. Sounds like normal behaviour.

Definitely normal for that age

My daughter was like this and even at 11 she is very specific with seams in her pants and a very clean child. There is nothing wrong with it, just be supportive and try to find clothes that don’t bother her as much. The clothing items did get better for my daughter as she aged☺️

She may be on the spectrum. I would use a smock bib its like a long sleeve shirt to help keep her clean while she eats or does messy play. As far as rolling up her sleeves it might be too restrictive whin you do that, will she let you just scrunch her sleeves up instead of rolling them?

That all sounds typical for a toddler. But if you’re specifically worried about OCD, you likely don’t need to be. OCD is characterised by intrusive thoughts, leading to obsession, leading to compulsive behaviours to deal with the intrusive thoughts. Our littles don’t have complex enough thought patterns for that yet! ☺️
