My bub was born in March and I had these awesome stretchy wraps. I found the only muxlin I had to be too small for anything bigger than a newborn. I got my wraps from Kmart and were given some other non stretchy ones from Target, these were also good.
I think wraps are great, DS hated them at the start and would struggle like mad to get out of them, but after some sleepless nites and nap times I tried it again and he loved it.
I think you will definately want some
