Share 'How does your baby/toddler sleep??'

So my daughter just turned 20-months on the 7th. We're now working on transitioning her out of her crib to a twin bed. The first couple nights were fine... she slept all the way through. Then we found ourselves getting up 2-3 times, one of us having to lay next to her til she fell asleep only to wake AGAIN!! What happened?? She was such a good sleeper in her crib!! I called the pediatrician toda…
