Re: Latching and Unlatching at end of each breast?
Sounds like a quirky nursing habit. Latching/unlatching may be your baby's way of getting the milk to start flowing again, or maybe he has discovered that latching/unlatching is a good way to get you to switch him to the other side or to get you to use breast compressions to get the milk flowing again. Either way, it doesn't sound like a big deal and is probably something he will grow out of. 11 weeks is still just the beginning, and a lot of "quirky" habits eventually disappear as a baby learns that he/she can get his/her needs met in a more straightforward fashion.
