Looking for advice

My little one goes to sleep really well on a night around 10pm and will wake up every night at 3/4am for a feed. We change her if needed and then she will have her bottle and drift off in the same way as she does at 10. Only thing is, she will only sleep for max half an hour at this point. Our day starts at 4.30 at the very latest. Is there anyway I can change the way I do my night feed to encourage her to sleep for longer than half an hour during the night?
