How many oz does your LO eat?

My son is EBF and has never had a bottle. He's 11 weeks. My dad is going to babysit him on Valentine's day so my husband and I can go on a date so we're going to introduce bottles to him this week. Just curious how many oz is most common for babies his age so I know about how much to warm up for him when we try the first time. Thanks!
