Hi hun, totally agree with Shiv. This happened with our DD, she STTN from 12 weeks for a whole month and then started waking for a feed again at around 4 months. We just used to feed her and then she would go straight back down and sleep through until morning. The feed gradually got later and later and she dropped it herself at around 6 months. Like Shiv said if she is waking up again so soon after you settle her and taking a good 4 or 5oz she sounds hungry to me.
