geekymummy - absolutely fine as long as she still fits in it well, and you're able to loosen it off abit if you're going say in and out of shops. they do sling blankets and suits, but i cant remember wghere. i;ll search on net and get back to you.
Loopsy - i found feeding easier in upright position as i'm a 30JJ and can hoick it reallt far up, but if you're unable to move it all the way up you can jsut bounce baby down, after you've loosened it. as for wanting to look around, that's fantastic what a clever one you've got!i dont mean to sound patronising but have you mastered slinging without trying to breastfeed in it? the easiest way for me to learn to bf in cradle hold was to do it sitting down with the sling wrapped but not around the baby to get LO used to the material being near, then everytime i fed to put a bit more matierial around him. until it wa eventually all around him, and then it moved to sitting up properly, sitting on a higher chair, standing but leanig against something and then walking. it literally takes 2 days, day one for the feeding and material, day 2 for the moving around.
Wulfric - the tighter the sling the better. you need to place him on your shoulder and drop one leg into the side of the cross that is the bottom one (does that make sense) and then his second leg into the outer one, make sure his arms go under the material too, then when pullin it across his body start at his bum with the under piece and move it all the way up his torso and then do the same with outer, making sure they overlap.
sorry if that doesn't make sense!
