My baby poo once a day on first mth but then poo only once per 2-3 days after full month..
Dr said some babies like that and normal as long as the poo is soft and Baby will fart always...(he got so many winds as well)
Now already 2 mth and seems poo issue improved (around once a day or once per2 days).. dr also advised me to feed some water (30-90ml max per day) as long as u feed formula...
I feed baby 30ml water a day as well..
