So need to get a bigger bed. The answer to my night problems would be to cosleep, which I'd love to do, but not sure about the logistics with two bubbas and just a queen sized bed.
you can do it, but yeah a bigger bed would be much nicer. could you bedshare just with the bub that needs it right now?

the no cry sleep solution has some ideas for all night sucking. the 'pantley pull-off' method was the only one i really had success with, but bub was a bit older than your little one.

i stopped nappy changes overnight around 3 or 4 months, unless there was poos.

if you don't think other baby will wake, can you swap sides if she still wants more? sometimes a fresh boob will give them enough to drift off.
