Bruise on babies lower back

I’d personally say no unless you have other causes for concern.

My son always has small random bruises but he’s always on the go and has minus levels of fear 😂

At that age when they’re learning to walk they fall and bash themselves constantly. My son had several black eyes learning to walk 🙈

Bruising is concerning in non mobile children.
In mobile children bruises are super common as they tumble and walk into things all the time. Like Yasmin says, unless you have any other concerns I’d say it’s normal.

At 12 months my baby was covered in bruises from crawling around and cruising.

I wonder if it’s just from failing over on something. If he fell on a toy he could get a bruise.

Most of the time it’s from a child falling onto a toy. At this stage they are learning to walk and are exploring m so there are lots of accidents just from the child making a mistake and learning. I work at a daycare and used to be in the room of this age and saw this happen a lot! Be concerned when it happens on a daily basis for your child and seeing more and more bruises pop up.

I’m guessing maybe from the shopping trolley aswell I’m not sure she’s fine in herself just teething x

Im 24/7 with my baby and i saw he has a similar bruise when i changed his nappies. No idea how he got it tho. So if its only this i dont think you should worry. Just pay attention if you see more things. Hope everything is fine

My baby gets bruises similar and sometimes it’s due to me catching him when he’s launched himself headfirst at something.
