Edison ma,
How are you? remember me? I'm one of the April 02 club mothers. my second one is now 2 months old! I breastfeed also but I feed him with half breast milk and half formular.
I wish I could also direct feed like you but difficult to change now.
Remember to rest more and drink a lot of soup and water!!! Take care.
There is also one possible reason: lack of vitamin D. "Your Baby's First Year" talks about breast feeding at great length. It says that exclusively breast fed babies need to be supplemented with Vitamin D drops, unless they are exposed to some sunlight. If they lack vitamin D, their brains will not be able to tell that they have enough food already...
