Congratulations on the new arrival! The method that I personally like to follow is to allow a full week before trying to feed and not handling until a couple of days after they take their first meal. This seems to be longer than most people like to wait to feed but I just like to make sure that they are full settled before trying to feed. It has worked for me in the past so I stick to it. Is the new one the female spider that is in your signature block?
