I have a 2 1/2 yr old that only gets to nurse before going to sleep. She needs it to fall asleep. A few months ago we started having latch issues (she's been cutting her 2 yr old molars). She no longer wants to fall asleep with her head in an upright positions (reduces teeth marks), she wants to tuck her chin. She also isn't taking the nipple all the way back in her mouth I suspect it hurts too much for her. Anyways we have been working very hard to try and correct this problem but it's not working. Does anyone have any literature or suggestions on how best to wean a child of this age in a caring and compassionate manner?
