I purchased this ring sling when my baby was 9 weeks old and she was diagnosed with hip dysplasia, this has been a life saver, it allows me to safely wear her whilst protecting her hips in the harness, she loves to sleep in it allowing for safe contact naps so I can get on with my day and the breathable material ensures that she doesn’t overheat. I have recommended this to all my current and soon to be mum friends. It also arrived quickly with a beautiful hand written note that was much appreciated!
