My LO is nearly 5 week old and is breast fed. She likes to just sit on my breast and suckle herself to sleep, as all babies do!! Im trying to stop this and seeing if i can soothe her by other ways i.e. via a dummie. Ive tried two types neither she will take, Mum and Tommee Tippee. She takes the TT one for about 5 seconds then spits it out. Does anyone recommend a dummie for bf babies??
