Baby not supporting on 1 leg

[DaddyDD]

Hi guys,

My 10 month old has been standing (supported) for a little while either holding onto the sofa or holding my hands and was pretty sturdy and stable on both feet
All of a sudden, a few days ago, they are not supporting any weight on their right leg and is either on tip toe or tries to avoid putting it down. Even when they are led down, that leg feels really floppy. They don't seem to be in any pain with it, but for the leg to go limp like that all of a sudden? Any help would be great

Scrap that, got him to stand on it and straighten it then put gentle pressure, then screamed with pain 😭

Ring 111. Could be a fracture.

A&E job, really.

That's definitely going to need an expert to look at it ASAP.

Out of hours / A&E I reckon.
