That's very difficult. It sounds like you've got lots of things going on at the same time and that naturally makes it all harder.

One thought re weaning: do you believe you'll get more sleep that way? It sounds like the lying down and feeding at night makes things easier. What will you do if you don't use the breast? You don't have to breastfeed if you don't want to Mother are often warned that their babies will wake because they're breastfed, but I think the truth more often is that they are awake, so they breastfeed to go back to sleep.

Do you have a sling or carrier to use during the day?

Is there anything in your life you can let go of, or give to someone else to do so you can have one less thing on your plate?

Hang in there. Hang in there. Babies do this, but it will get better.
