I have an Ergo which we loved with DD1, but I only got it when she was big enough to go in it without the insert. I need something I can breastfeed DC2 in - should I get the insert for the Ergo, or a Moby/Kari Me? We already have a Wilkinet & a Baby Bjorn, so I do have slings we can use from birth but that I can't breastfeed in.
