I actually tried the hip carry with my almost 8 week old today! All of a sudden she wants to look out and doesn't want to be tummy to tummy when using the ring sling. She usually likes the kangaroo carry facing out with the hotsling but today she wasn't diggin it. So I grabbed the ring sling and tried a hip carry! She was actually able to do it (she seems to have good head control for her age!) but she was in a grumpy mood and didn't like any carries today!
