Hi Jac, I find the it's the opposite problem! My DS#1 can sleep through it all unless it is close to getting up time anyway. But if he makes a noise in bed he wakes our bub up .

I think toddlers are a lot like Dads, they can sleep through the baby crying LOL!

Try not to stress out about it, you will find a way to make it work, you'll be amazed! Good luck
