I have seen quite alot of mums wearing their bubs around where I live since becoming a mum, probably cause I am a mum I have noticed it more. Wrap Baby slings are quite easy to buy and I have even seen the pouch slings in the generic stores like Target and Kmart, Baby Bjorn-type carriers are very easy to find here. I used to wear my bubba but now, at 8kgs, and with some back probs, she's just too heavy!
PS. I live in Aust!!
