I know this is a crazy question, but I have been looking at slings, wraps etc. and I can't help wondering if babies can fall out if you lean over while wearing one? (e.g. to see to a toddler) I really want to get one for no. 3 (due any time) to do the nursery run with my 4-y-old, as I also have a 2-y-old and need the "extra hand". Have been looking at babaslings? or ring slings? all v. confusing. Baby is predicted to be quite big (I am not!). I don't quite understand the logistics of how you can move around, bend, stretch etc. without there being a risk of baby falling over side of sling, since there are no straps. Can anyone help put my mind at rest and/or recommend a particular sling? Thanks very much!
