I've just found out I'm pregnant. At the moment I carry 15 MO DS around in a patapum, but I can't see how the waistband is going to work with a bump. I need to use a sling to get him to the childminder's by public transport and foot; taking the pushchair is out of the question (too many stairs on the journey and nowhere to store it at the CM's place) and he's too little to walk.
Does anyone have any suggestions on what would be a safe and comfortable alternative? DS is a lightweight (25th centile) but tall.
