I am entering my second trimester, and I have just started thinking about what things we really want and need for the baby. I would prefer to wrap my baby up like a giant burrito rather than use one of those baby backpack things that leave their legs dangling. I have heard that those aren't good for a baby's reproductive organs, because it focuses all of the weight and pressure in that exact area at a time when overall development is so important. So I need to make a trip to the fabric store to buy a very long piece of sturdy cotton jersey knit. If anyone knows the exact length of fabric needed for this please let me know.
