Ergobaby is a good choice for parents with back problems. A friend of mine suffered from hernia and had problems babywearing his baby girl. But his wife researched the benefits of Ergobaby and he has no problems with carrying his baby anymore. He also said that he started off babywearing 5-10 minutes at a time and slowly increased time as he got more and more comfortable. Try not to rush into it and babywear for too long if your back starts to hurt.
