Can I check if anyone just change from nan 1 to nan 2 and baby cannot finish drinking and have difficulties to poo and he poo abit by abit ?

Not now but in the past for my #3. He doesn't seemed to hv problems pooing. His diet is very important. My boy takes lots of vegetables and water. I reduce the no of scoop of milk powder by 1 scoop. This makes it less heaty.
