My daughter is 13 months, she got teeth very early...four months, and I have had trouble with biting ever since. As she gets older I can tell her "we don't bite," end the feeding and she usually gets a very hurt look and starts to cry. I wait about a minute or so, then I repeat "remember we don't bite Mommy" and let her nurse again. This is getting better, but as she cuts her molars and if she is really over tired, it becomes a problem again. I love nursing and I know how important it is for her, so I just grin and bear it most of the time.
My son is getting ready to turn one year old and I still have a problem with him occasionally biting my breast when he nurses. Usually I tell him "No biting" and if he does it again, I end the feeding. He has gotten better about not continuing through with the bite. I have had some people say I need to flick his cheek, but I cannot bring myself to do that. He is very sensitive and it would desperately hurt his feelings.
As a LLL Leader and mom who begins to experience rather noticeable nipple pain from ovulation until my flow begins, I am wondering if there are more out there with this issue. I had problems once with nipple candidiasis [thrush], but this is different, abrupt and noticeable, and sounds much like the feelings moms have when they are pregnant.
There has been some discussion of this on Lactnet and mention was made of calcium, magnesium, and Evening Primrose Oil as potential remedies.
It is very strange to suddenly feel nipple pain at 13 months, only to realize one's fertility has returned...it is also upsetting to plan to nurse for years after this begins!
[P]regnancy may cause nipple soreness from hormones; so can the hormones at the time of ovulation. . . . thus, a day or two mid-cycle. . . . I have this and know others using natural family planning are aware of it. I've been a Leader since 1986 and am grateful to have read Sheila Kippley's book Breastfeeding and Natural Child Spacing.
