Well my ergo came yesterday <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/thumb.gif" style="border:0px solid;" title="thumbs up"> but I have a few questions. Does the hip/waist part go on my waist or on my hips? Also, should I be pulling the waist part really tight? It feels comfy if I do but gives me a HUGE gut!!!
