DH and I always used to joke about how different DD's poos were from one to the next, even though the only thing that went in was breast milk for 6 straight months. My DD was quite similar, maybe not as explosive, but you could hear her let go a mile away. It wasn't until around 8 months (we did BLS) when the texture finally got more solid as she started actually swallowing food. I had to stop myself texting DH at work to tell him her poo had changed

With that said though, if you think something isn't right, maybe you could talk to your health nurse or GP?
