Toddler and baby sharing room

C

I have a 3yr old and an 8m old. I’m not ready for 8m old to move out of our room yet (she’s had medical issues and for me I’m not ready). But when I am, how did you go about having them in the same room. 8m old still wakes a couple times a night to nurse. I just don’t want her to wake up my 3yr old.

Sound machine is on all night along with a fan. She’s in a love to dream sleep sack.

I will be getting a new camera. (Current one doesn’t hold charge well).

What’s an easy way to transition baby to a shared room with her 3yr old sister and not wake each other up.
