Your baby is falling out

I am attempting a new tie for the sling, with Anna on my back. On my second attempt, I was going through our neighbourhood and a guy driving by rolled down his window and said, "your baby is falling out". Anna then shifted to be more upright, and he said, "oh, she's okay now". Too funny. It doesn't look totally secure, but she really is in there tight. I have loved this sling, but I think it is time for something with a bit more structure, so I have ordered an Ergo Sport. I will be able to carry her on my back with that one, as well. I am looking forward to more walks, but now in nicer weather!
