Pediatrician said 2 naps only

My son is 13 weeks and isn’t sleeping good at night. Wakes every 1-2 hours. I beleive it’s just a regression and a reaction to the change of dad returning to work. He gets 4-5 (5th is short) naps a day, 4-5 hours of sleep, and his bedtime is consistently around 8-9pm. At his pediatrician appointment today, she said he was getting too much daytime sleep and he should only have 2 naps a day. One in the morning and on after lunch. She also said that contact naps are setting me up for failure in him being an independent sleeper in the future. I was just a little taken aback because I had read and heard that 4-5 naps at this age is normal and he doesn’t get too much day sleep. When we’ve tried to drop down to 3 naps a day, he’s overtired and sleep is much worse at night. Is his pediatrician outdated or is 2 naps doable? Would it help?

I don’t even think my son could stay up that long anyways. His wake windows seem to be on the shorter side, but he has sleep cues (yawning, red eyebrows, rubbing his eyes/face). Really concerned with her suggesting to make him that overtired.
