I think babies temperature is higher than adults. Me freezing there while my baby’s neck feels like she’s sweating 😅 I wear normal footed PJ and cover her with a thin muslin blanket (which she kicks off all the time). She’s more afraid of the warm than cold.
Me too, we sleep in AC room with medium-speed fan cause we get warm easily especially my husband. So I dressed baby in footed sleepsuit with a cap and wrapped her with muslin swaddle. She slept soundly, no issue for me.
short sleeved/sleeveless onesie swaddle. if no swaddle sometimes just the onesie alone, if it's a cold night then sleepsuit
When i swaddle baby, i let him wear sleeveless romper. Once off swaddle, i let him wear jumpsuit alone.
