a friend of mine her daughter weaned because she said 'baby needs it! im ok' every time the toddler wanted a drink bubs would cry.

also another friend(yes i have a few tandem feeding friends) she co sleeps with both her children so would just roll over to which ever one needed it.
they had a queen size bed with a single next to it.

im not sure if youll get any sleep! i feed only one and dont!

good luck with it !
