My 6wo hates his sling. We have the Caboo lite and I can't ever get him to settle in it. We always start when he is calm and/or asleep on my chest but once I get him in he screams and continues to do so. I'm not totally confident I have him secured in it properly either, when I take a deep breath it feels tight but his weight falls forward and down rather than being tight to me. I never get anything done, I need this to work! Any tips?
