i have an ergo which i use for DS (still). he loves it and i find it really supprtive etc.
I looked into getting a newborn insert, but they werent really recommended highly by friends i have who have used them. they thought if i wanted i could roll a cloth nappy and achieve the same thing...
anyway, i bought a close carrier which i will use for this bub as a newborn and then i will have the ergo for later... (or another option to use in any case)
