Timid toddler seems scared of other children?

[Gingerninja01]

I’m really worried about DD 2yrs old and am hoping for advice from others who’s children are of a similar temperament and reassurance really.
She is exceptionally timid around other children. Not so much around adults, although she does have occasional moments of not wanting to look up at strangers and burying her face in my chest etc, but around other children I can only describe it as if she’s frightened.
She is an only child but has been going to regular baby/toddler groups since she was 3 months old. She physically flinches when children play/run near her, and more recently will act panicked and shout “mummy mummy I need a cuddle!” and ask to be picked up.
She’s not had any negative experiences such as being hit or pushed around by other kids which might explain this.
She’s got a friend of the same age who she sees regularly since birth who she loves and who she is completely different with, she is actually if anything really loud around her and interacts really well with her.
I don’t view being shy as a negative personality trait at all, but I am worried that if she is still this timid and seemingly scared of other children when she starts nursery/school, other kids will pick up on this and will start picking on her, which I couldn’t bear.
Does anyone have any advice around this please?!
Thanks!

OP I have no experience so my comment may be useless but the thing I would make sure is I didn't make a big thing about this. So yes reassure her if she needs it but I wouldn't be making her feel like there is a justifiable reason to be scared. I am sure you don't. But I mean don't go "oh darling it's ok there there mummy loves you" etc etc and making a big deal about it. I would simply offer what she needed but maybe go "oh look at that little boy running around playing with that toy car isn't he funny, he looks like he is having a great time" or something. Play it cool. Again I don't have experience but my 9 month old is unsure of other babies and children and this is what I do with him. Who knows if it's right haha.

I sort of have one of these. Shes nearly 3. She is much more timid around adults though. She was worse with children when she was at nursery (flinching when they walked past etc) but I pulled her out and her confidence seems to have grown. She now plays nicely with others, a bit shy but not scared. She is still painfully shy with adults. I honestly dont know what to do about it, I just let her bury her head into me if she wants and I dont force her to talk to anyone in the hope she will just get over it one day.

We’ve literally just got out of a “phase” of this. I spoke to a HV who reassured me. Nothing changed I just persevered with taking her to toddler groups and she just got over it. I’d say she was like it for a couple of months
