S.K.
Our twin girls are now 4. I remember those early days. I didn't read everyone's responses so hope I'm not repeating. We had one who slept soundly and the other didn't. We swaddled them both and we put one in a cradle in the living room with my husband (the sound sleeper) and one in the pack n play in our bedroom with me. That worked for a while. Then they began crying when we would lay them down to sleep so we let them sleep in their car seats. It worked wonders. Keep the lights very low so they don't fully wake up when you feed them and try using a fan for white noise. We still use one in the girls' room.
Congratulations on your baby girls. It is tough for the first 3 months or so but it gets easier. This too shall pass.
Blessings to you and your family!
