Help! Need a bit of direction in helping look for the perfect sling (if it exists). I have a 12 lb 9wk old DS & I use a Moby. I'm finding that it's a pain to put on & would prefer something less hassly. I have a bad back so need something supportive which distributes DS weight well. Would love to be able to feed in it, though this is the least important 'want' on the list. I live in NI & don't think sling libraries exist so can't try various styles before buying...TYIA
