Baby wakes at 4am

Mr

My almost 5 month old son will fall asleep every night at 5pm. I try everything to keep him up but he is sooooo ready for bed by 5pm. He still wakes up 3-4 times a night for food. But since he goes to bed at 5pm he’s up by 4am! I tried so hard to keep him up longer last night and he made it to 5:40pm, so he was up at 4:30am. Will he grow out of this? Any suggestions?
