About 3 naps. In a sense, you are doing sleep training. For my LO, if my husband and I put her down at the sweet spot, she goes to sleep in less than 10 minutes on her own, sometimes without any whining/crying. We chart the sleep durations and awake intervals, so we know her pattern, but also look for sleepy cues. This applies also to when she wakes up at night for feeds (2-3x/night). After feeding, we put her down awake and she goes to sleep on her own. The toughest one is still the final putting down for bedtime in the evening. Her resistance to falling asleep is the strongest (lowest sleep drive even if she’s tired), so she cries longer.
