Pip, I did exactly what clever Rach has shown you ^^ it works really really well.
K now has his legs out cos they're long enough and he much prefers it... but it's only been in the last two weeks or so.
Yay for babywearing, hope you and S love it
The only thing I am not sure about the Mei Tai is the way the strap goes over and under LO's legs. Looks like it might be a bit uncomfortable for him.
