wow Suze! thankyou so much for all that info it is wonderful!! You have goven me a whole lot more info than i have been able to find on severzal internet sites. I have thought a lot about it and tried him in just a home made sling and I am going to give carrying him a miss, he is just SO heavy. Am hoping to have a new bub next year so will carry bub from birth in an appropriate sling.

Thanks everyone for your advice, will certainly buy an Ergo next bub as everyone seems to rave about them.
