I am trying to figure out which bedroom to put my newborn in when she is born. If I put her in the room right next to the master, it is a much smaller room. If I put her in the larger room, she will be right next to my 2 year old. Will she wake her up then? She will be in the pack-n-play in our room for the first couple of months.
Re: Does your newborn wake your toddler up crying?
I have a 3 year old and a 7.5 month old and they have rooms right next to each other. I stressed just like you are doing now but they have never once woken each other up from crying. I have a box fan in the toddlers room which drowns out noise and a white noise machine in the baby's room.
And I haven't noticed any sort of sleep regression in my toddler. He's always been a great sleeper though.
Not common for us. Nothing changed with my toddler when the baby came. (He was 2.5 at the time).
