Baby suddenly poops way less


My baby had a big change the moment he hit 3 months. He always used to poop 3 times a day (except for the first few weeks where it was like 6 times). Now it’s like once a day, sometimes a little longer. When he does poop it looks fine, sometimes it explodes. He still produces TONS of pee and is exceptionally happy, still not sleeping through the night, still eating a lot. His personality also changed and now he is using hands and feet, laughing, and screaming when he’s mad.

Is this just normal stuff that comes with turning 3 months or is that separate and worthy of concern?
