I didn't own a cafe/food business but I did launch my own biz when my bub was 12 wks old and it involved expos and things like that and she went everywhere with me. I would suggest you invest in a couple of good baby slings to suit different situations. Start with a wrap style like the hug-a-bub (basically just a long piece of material) or other newborn hugging sling - something that distributes the weight evenly over both shoulders and offers you flexibility as they grow. Once they are able to sit up there are a range of good carriers, the ergo is one but I know other ladies here have got some others that they have used that are great - they can do front carries, side/hip carries and back carries.

I think the easiest time will be when they are little and just want to be held and sleep. Miss A spent most of her first 6 mths in a sling either at work or doing housework at home lol.

All the best!!!
