Neither of my boys really got into a napping "schedule" until they were 4 or 5 months old. The first few months it was kind of all over the place. The first consistent nap that I noticed was a longer morning one a couple hours after they work up (usually slept 1.5 hours).
By the time they were 6 or 7 months they were having 3 consistent naps a day (awake at 7am, nap#1: 9-10:30am, nap#2: 12:30-2pm, nap#3:4-5pm, bed by 7:30pm). By 9/10 months both had dropped the 3rd nap with a longer second nap, and the morning nap was dropped around 15/16 months.
Good luck!!
