its going ok for me but sometimes at the end of the evening I feel so DRAINED from nursing the baby and the 2yo. For a few weeks there I literally felt like I was nursing non stop from around 6pm to 10pm. That is getting a bit better. My older nursling is 2.5 so she is old enough to understand some limits on the nursing though I am not super strict about it. I generally just nurse her before bed, before nap, and when she wakes up in the morning if she thinks of it. She is really, really into nursing at those times but pretty well accepts the limits.
Sometimes I nurse them together but not often. Today for naptime I rigged up a two-layer side-lying deal with the baby on the ergo infant insert next to and slightly on the bigger one. Ugh. I really don't enjoy double nursing like that but the girls seem to really like it.
I heard my older telling her dolls she can nurse "two girls" and then sat there nursing two of them together. Sometimes when she sees me nursing the baby she asks, "how about two girls?"
Bigger girl is also kind of picky now- "that one tastes funny" etc. Apparently one breast has a different tasting milk?!?
Little baby is a great, avid nurser, good latch, I have no complaints.
Oh and yes, toes curl in an icky way from the older nursling sometimes. Her latch totally didn't bother me before but now, yuck. I think with the milk in she is sucking more and so I notice it?
