i saw a woman (american, i may add although that's neither here not there) using one of these the other day and the first thing that sprung to mind was HOW RIDICULOUS.
honestly the faff you need to make to get the thing in place, often when your baby will be screaming for a feed, is guaranteed to draw attention to you and the fact you are about to breastfeed. so if you are shy it's just going to make things worst in my opinion.
add to that the fact that your baby may hate it- some babies just don't like being constricted.
but for me the overwhelming argument against these contraptions is that they play on some kind of accepted argument that breastefeding is a shameful thing and you should cover up and that really drives me insane. it is in my opinion one step away from forcing women to go to the loo to feed or to stay at home!
i am not saying you won't feel a bit self conscious to begin with- you will. with my dd i waited till i was quite confident in my latch and positioning before i started bfing in public and in the beginning i think i used a shawl or a muslin to cover up- but when i got more confident i just pulled up top quickly, pulled down bra and off we went.
have you ever seen a woman nursing in public? can you honestly say that you've seen much flesh? a woman nursing in a natural and relaxed way is i think very discreet- much more than one layered in a weird sheet of fabric and looking self-conscious.
sorry- i realise i've come across very harshly. it is not meant to be against you Orissiah, but rather against the product. i'd say save your money for a lovely scarf or pashmina and use that to begin with- and come back in a couple of months to let us know how you've ditched it for bfing and are "only" using it to decorate your neck!
