Honestly, don't worry too much about this. If you are comfortable in that temperature, chances are that the baby will be too. All babies are different, but i know that after they are born, they like to be swaddled and warm, because they are so used to the warmth of the womb. Your baby will let you know when something is wrong. For example, if you have too many blankets on the baby, and he/she is too warm, he/she will cry and let you know that there is something wrong. Also, if the baby is sweating, then of course you will know. Just do the best you can, and your baby will let you know the rest.
Good luck and take care,
