Hi All and Elizabeth, What I would try would be suck training in this fashion: Have mom or dad let baby suck on their finger (if dad has big hands the pinky is best)(please make sure nails are cut VERY short and hands are clean). Finger should be well in babys mouth, to the s-spot, juncture of hard and soft palate, or about the secong joint on the finger. Baby may have a strong gag reflex so they may need to desensitize babys gag reflex by slowly increasing the amount of finger in babys mouth. (had to do that with my kid) While baby is sucking finger should ever so slightly (so slightly that parent feels almost like they aren't doing anything) pull forward (as if trying to pull out of babys mouth). this teaches baby to get used to having the back of mouth filled with something that later will be breast. When mom BF have her try the nipple sandwich technique to get more breast in babys mouth and farther back. This will, hopefully, help with the sore nipples! Good luck! Jay whose been there done that!
