I've got a Yogabellies wrap sling and just can't seem to get DS's head in the right position. He always seems to have his face buried, even if I've got his head turned to the side. Can anyone help? I'm pretty confident I'm tying the sling right but have tried it higher up my body and lower and it doesn't seem to make a difference. I'm quite large of nork so I'm wondering if this is putting him in a weird position? I want to be able to walk the dog with DS in the sling but am worried about him suffocating!
