Re: Not acting full
As long as her weight gain is good, I'd say that what you describe is normal. Frustrating but normal. One possible explanation for the behavior is that your baby enjoys a nice long session of comfort nursing after she is done actively eating. Have you tried switching her from breast to breast and then back again when she exhibits this pattern? That might make her really fill up and release the breast just because she can't stand to hang out and nibble any longer. A pacifier might also help her let go of mama, if she'll take one. But a lot of babies won't- and why would they, when mama is so much nicer?
