how much do i leave

So tomorrow night is my husband's 30th birthday and the first time that we are going to be out during the time little man goes to bed. My mom is coming to keep him and she is wonderful with him and follows my guidelines. He goes down for naps easily, However i have always nursed him to bed for nighttime. I have no idea how many ounces he drinks during the day let alone for bedtime and with comfort sucking. So my question is how much should i leave in a bottle? any tips for my mom? We will be close by and if he doesn't go down i can always come home real quick.
