Worried about bruise on baby

[Newmum23x]

Advice much appreciated!
Last night I was getting my little one ready for bed and noticed a tiny bruise on his side, he’s not done anything that I can think of to give him the bruise so I have been worrying about it since (especially after googling). He is almost 10 months and moving around alot and into everything but I’ve just noticed another on his elbow this morning!! Does this sound normal for a baby his age or should I be worried and call the GP?
The mum guilt is real as I feel like I should of noticed if he’s done something to cause a bruise.
Thanks so much in advance!

At 10 months they are active with no proper coordination or control. Very normal for bruises.

How much is baby walking or crawling?

Is baby mixed race at all? My dsughter had strange bruises on her back at about that age, took her to gp and he said they were mongolian blue spots which are harmless.
I mean if the bruise is tiny i wouldn't worry too much keep an eye on it tho

He’s not walking yet but very mobile on the floor, he is into everything and always rolling so could probably be from that!
He’s not mixed race but the mark you mentioned sounds similar so it could be that - thank you so much!
I think it’s because I’ve noticed the one on his elbow too I’m just in a panic!!
