Two children sharing a room

Brittany • Mama of a beautiful baby girl and another lil babe on the way💕

Anyone have their toddler that will be sharing a room with the soon to be 2nd baby? My daughter is a year and a half and will be sharing a room with our second daughter as well. Obviously not right off bat as the baby will be in my husbands and I’s room for a couple months. Just wondering if you had issues with baby waking up toddler in the night, any issues at all!? We just don’t want to put one child on the lower level in their own bedroom quite yet as they’re are both still too young
