It's up to you really. We just had a sippy of water by the bed and my two boys drink milk on demand throughout the day. I didn't really want to get into having a big drink of milk before bedtime as it really doesn't help with night time dryness. But your LO is young so you probably aren't thinking about that just yet.
You're looking at your LO having three portions of milk or dairy products each day. One is the morning BF, the other two might be cheese or yogurt or a cup of milk (or on cereal).
