Before-bed feeding takes forever

Does anyone else’s bedtime feeding take an hour or more?? My baby is just shy of 4 months and nurses in about 8-10minutes during the day, and that will keep him full for 2-3 hours. But when it’s bedtime, he will nurse for almost an hour! He does all asleep here and there, so I have to constantly bother him so he’ll stay awake. But even still, he’s such an efficient daytime nurser that I don’t understand why our nighttime feed takes so long. I’m considering switching to bottle feeding before bedtime.
