Sleep

Best to separate if possible because you might be disturbing the toddler's sleep during your baby's night feeding. If either 1 of them is sick, the other might also get it quickly if they are together.

Is okay to put them together but it will affect the sleeping quality of your toddler if she is a light sleeper especially when your newborn needs to wake up often for milk.

No problem for me. Both sleep in the same room. Newborn with me, toddler sleep on a single bed place next to my queen size bed.

Better not. Toddler when they sleep they wouldn’t care about the space.

Agree that for safety it is best to separate them in separate rooms

Yes but waking up each other may cause disruptive sleep for all

No, u have to separate them. Let them have their own space.

Nope try to separate them

Depend on individual

Best not
