especially if you're carrying your baby on your back? Both me and dd (5 months) love going out with the sling and I don't find her heavy but once you have all the usual stuff to carry (nappies, spare clothes, purse, keys, water, snack for ds etc etc..) it's not that great and means you're a bit stuck if you want to buy anything at the shops while you're out, go to the library etc. because you end up looking (and feeling)like a pack horse! If I go into town I usually take the buggy as well which seems to defeat the purpose a bit!! I'm quite fancying a sling that can do back carries as well but then I couldn't wear a rucksack for the stuff. What do other people do?
