I don't know what I'm doing wrong but with my first DD who weighed 9.3 at birth and now again with my second DD who weighed the same, I can't find a sling that works. I have tried lots of different types but my babies cry and squirm in hammock type slings that all seem too small and squash them - my second DD is on the 99th percentile for length. But because DD2 can't support her own head yet, I don't want to use something like a Baby bjorn because they don't provide any head support. I also have a Kari-me fabric sling and I just can't get the hang of it - DD just slips lower and lower until she's hanging around my crotch no matter how tight I have the sling! Plus I find it so hot - we both end up boiling hot. The Babasling I have just squashes her in the hammock position and in the upright position it doesn't support her head. What am I doing wrong! My DD wants to be carried all the time but I can't do it without a sling. Any suggestions?
