hi there,
first of all (((HUGS))) to you. sounds like your baby is doing fine, so i think you should focus on your toddler. here are a couple of ideas i had as i read your post:
- drop the milk at night
- i would check out the pu/pd board for tips on how to help your toddler go back to sleep at night (may want to check the toddler sleep board too)
once you have some ideas, formulate a plan, and then stick to it all the time. it will not appear to work at first, and things may get harder before they get easier, but if you are consistent all the time, you will have your toddler sleeping all night so you can focus on your baby & your own sleep as well.
HTH a little...
