Mines been the same. It's only when he is constipated that it might be hard/formed. Else it's always soft.
Ours poops in potty 99% of the time and that looks like an adult one. But the occasional nappy one looks soft. Guess it just gets squashed out
Oh this makes me feel a lot better my little girls is still soft she has gone through periods of constipation but mainly soft and very colourful depending on the food she has eaten
We get the occasional formed one but mostly still soft. I'm not sure either whether it's normal. Food definitely seems to have a big impact as they often very quite a bit in colour too.
