2 month old sleeping

Melissa • Isaac 09/09/2016👶💙
When did everyone start a sleep/nap schedule for their babies? My baby is 9 weeks old and he has about 3 naps a day but they all last for about 3/4 hours. He has one in the morning, one early afternoon and one early evening. When he wakes from his early evening nap, around 7/8 he stays awake and fights going to sleep until about 11pm sometimes later. He then wakes up once sometimes twice through the night, should I start waking him up earlier from his naps or is this fine for a 2 month old?
