Some babes are just very "booby minded" I swear.
When my DS was born (he's now 16mos) he latched on at about 5mins old and stayed there switching between breasts for 2 hrs! It can be a little aggravating at times when it feels like all you are doing is nursing, but i try to look at it this way: You are the reason your baby is thriving, you provide all that he/she needs by the grace of nature and the miracle of your body. Nursing is one the most wonderful times as a mother. (And I second the nursing with a sling! Such a lifesaver! With 6 kids, one 7days "late" and my 16mo old still nursing, Im looking forward to being able to feed a NB babe and get my laundry folded!)
So glad things are going well for you!
