My ds is 3 months old and already 17 pounds. He LOVES sleeping in his sling and I think he still needs that feeling of security sometimes for naps. However, he is getting very very crammed in this pouch. Is there a hold for a wrap that a big 17 pounder could still fit in "cradle hold" style? He likes to lean back like this to sleep. We may have problems if I can't find a cradle hold to accomadate his chubby little body!
