Does changing formula change poop colour?

My daughter was on Cow %26amp; Gate Stage 1 formula, and has been since birth. Her poop was always bright golden yellow coloured. We switched her over to Cow %26amp; Gate Infasoy (Soya milk formula) yesterday at 4pm because we found out she was lactose intolerent. When she went #2 this morning her poop was mostly yellow but the last bit was sort of a light snotty green. (She did a poop with her nappy off, thats how I know lol)



Would switching to Soy have changed her poop from yellow to green?

(She's 6 weeks on Wednesday)Does changing formula change poop colour?yes it could.switching anything the child eats or drinks can have an effectDoes changing formula change poop colour?My doctor told me that if it is kind of green rather than yellow then it means that it is passing through the system faster... and that it is OK. Time to worry is if it gets dark... like brown or black cause that could mean it is taking too long to pass through the system and possible constipation... or other serious problems.
