I used nipple shields for the first 5 weeks as bubba wouldn’t latch otherwise .. I used these ones - https://www.amazon.co.uk/gp/buyagain?ref_=navm_accountmenu_buyagain I found he latched reslly well to it however it kept unsticking and flapping up covering his nostrils .. I found it so annoying, but he got on reslly well with the small size x
I found the mam ones really good and so simple to put on x
I have both the MAM ones and the medela ones, I prefer the mam ones as they stay on so much better and baby latches on them better xxx
