My 2 yo DS has not shown any interest in going back to nursing since his sister was born 2 weeks ago, and seemed to have forgotten how to latch. I've pumped a few ounces a day for him so he could at least have my milk again, and he has definitely been enjoying it, even asking me to pump more. Then yesterday at nap time, when it was just the two of us, he latched on and nursed like he might never get to nurse again. Then again this morning, while his sister was nursing, he latched on to the other side and nursed again! His latch isn't great, but it IS a latch. I'm just so glad he's going to get the opportunity to continue nursing until HE's ready to be done.
