Hello ? I don't know what to do anymore, we're on the toilet, before it was every 2,3 days, and sometimes even daily. Now for two weeks we can say that we haven't pooped, in that week I didn't poop for 6 days until I put a candle, today started again for the 6th day as if we haven't pooped, he doesn't suffer, walks, eats, laughs, only sleeps badly at night, this is not like us at all, he doesn't cry, just may wake up and I can pump him five times in a row, and with each time he falls asleep, but still doesn't cry
