Hi B., My name is K. S. I am a mom of 2 boys (13 and 9), both on the autism spectrum disorder umbrella. When they were babies, I never put them in sleepers. I felt it was too constricting for them. I put them in onesies and little footies. Never put them in nighties. I tried it, they kept waking up alot more than the usual feeding times, then I tried without and then they only woke up for their feedings. To this day, they don't like anything on there legs. Oh yeah, and when they were babies I had the air on 76, 77 during the summer and 72, 73 during the winter. If you leave your air on at 75, it will cause your electric bill to go up. Hope this helps.
