Once you put your baby to sleep for the night, if he wakes up you can nurse to sleep, unless he is old enough/able to go by himself. The rule is to put them awake or almost awake to bed at bedtime, this counts. You can't really expect from a newborn to sleep through the night or have an activity after the feed in the middle of the night. You want him to understand that night is for sleeping, not for an activity.
Most babies have a natural need to cluster feed in the afternoons or early evenings to tank up for the night. It is up to you and your lo if you put him for a nap after a cluster feed and then wake him up again. In my case, dd was cluster feeding in the late afternoons and she didn't nap, this was her most active time of a day :? but this is just how she is and I am, we are evening persons. Then she had a feed before sleep, pajamas, went to sleep. I was not waking her up for a dream feed, only picking her up in her light phase of sleep, then she nursed, even if she accidentially woke up, she would go back to sleep while nursing. This is OK, you want your lo to sleep at night.
