She is staying in our room, the A/C is set to 76, and the ceiling fan is on. She'll be in a bassinet.
Every class out there says no blankets in the bassinet (but they swaddled her in the NICU...which seems contradictory).
Help me please...I don't know what to dress her in, and whether to swaddle her or not.
Re: How would you dress a 4.5lb baby for bed?
Gabe is going to sleep in the following:
Onesie, socks, sleeper (with or without feet) and swaddled in a blanket. I am a super tight swaddler. We also have a woombie (preemie size) and a sleep sack (preemie size) that we can use.
We'll miss you sweet Debbie Girl (4.21.12) and sweet Cindy Girl (8.9.12)

I'll tell you what our OT said told us as we were prepping to go home. She said that babies usually get too hot rather than too cold when they sleep. She said no swaddle, even though yes they do it in the NICU. She said she's tried to talk the NICU out of swaddling for a while but they won't listen. Since your DD will be in a bassinet rather than a crib I'd put her in a sleep sack. I hope that helps.
Also, we still swaddle DD even though you aren't suppose to. We got home and tried to get her to sleep unswaddled, she was not having it.
Oh and DH is and HVAC tech and he was always inquiring about what the temp should be in a home with a preemie or newborn... the nurses always said 72-76 would be appropriate depending on how they are dressed.
We came home at 4lbs 6oz and 4lb 8oz. We set the temp to 76 and dressed for bed in footed sleeper and fleece halo sleep sack. At every diaper change I'd feel their feet. Sometimes they would be cold and we'd add socks.
You can swaddle with a traditional blanket until they can break out of it. At that point you need a swaddle blanket or sleep sack swaddler.
I cringle at the thought of having to break swaddling.. mine won't sleep without it.
