I've tried a sprots carrier, ring sling, and wrap and the mei tai is the best of all. easy to put on (easy enough for DH), small and light to carry with you. DS loves it, and is happy to sleep in it, it's super comfortable as his weight is distributed across my shoulders, back and hips, and it was really cheap as my mother made it using instructions from the internet.

My baby loves it, she has a big smile when she sees it come out.
