Your LO may not like being worn at all, but if the crying happens when putting on the sling or wrap, you may want to stick with it. My DD loves to be worn, but it took a while to get there. At first I thought she hated it - as a newborn she always cried going into the wrap or sling, and I'd have to bounce around a lot to get her to quiet down. Most times she would settle in, but sometimes we had to bail out. Pretty soon, though, she loved it, and at 13 months is still napping in the Ergo carrier. I think it was the awkwardness of putting her in that got her upset. Just a thought.
