Teething Question

ns1

I think DD is teething.  Her gums are red and I can see white bumps in the front part of her gums.  Daycare also noted she was fussier than normal today.  I noticed this weekend when she was nursing with me she seemed to take less than normal, which I've read is normal while teething.  But, today at daycare she took her bottles with no problem.  Could nursing less from the breast still be from teething?  or not if she still takes a bottle fine?
