hi can anyone give me any advice about slings, i have a 2 week old baby and a dog and when walking the dog and the baby on my own i could really do with a sling, i have tried a couple of basic mothercare ones but they are all very uncomfortable, can anyone recommend a solution, the hug a bug comes up second best in the find the best section?? but looks like the huggababy might last longer? dont mind about cost so much concerned about comfort ane ease of use, thanks
