Many of my friends gave up after a couple of weeks or so b-f.ing, they wanted their husbands to take more of the work by bottlefeeding!!! So my tip is to think of the bonding you get between you & your baby that no one else can get, they way he looks up at you when he has mouthful of milk, satisfied! I used nipple shields for 13 months on ds1 & tried sooooo hard not to with ds 2, now 4 months, but the pain was so excruciating, I had no one to help me (foreigner in foreign land!) & I spent all my time crying. Sooooo I went back to nipple shields & hey presto, success. he is a fat & healthy 4 month old. Ds1 very healthy too! So, to mums like me, don´t worry about nipple shields, if they work for your baby, then use it!
