DS2 (15 weeks) used to love to sleep in his sling (coorie and tricotti) but is now far to big for it. He seems to want to sleep in cradle position rather than upright but obviously this is impractical at his size (over 16lbs) - any suggestions for a sling that he will be really snuggly in for sleep. I think it may take him a while to get used to sleeping upright rather than cradle but if it was really comfy maybe he could be persuaded!
