That's what we did. Our baby was doing the well known spraying right after removing the diaper the first few days. So we decided to put him on the potty on his second week following advices of parents who did that too: timing, sound cues... In his second month, he already understood the patterns. Since then, he will sometimes pee in the diaper as we are not doing the zero diaper method and he understood it's not that uncomfortable to pee in the diaper. He will poop in the diaper once a week when we are too distracted or when he is having digestive issues with a newly introduced food. No smelly trash, never waking up with a diaper full of poop, no red skin, happier baby. Highly recommended if you have the right environment to implement this method.
