Hi all my dd is 6 months, EBF, until I started weaning her 2 weeks ago. She has also cut two teeth in past two weeks. Her poos are explosive. Really runny, mucousy & always up her back. I could go through 4 nappies during a feed. Her solids are just baby porridge, fruit & veg at the moment. I don't remember my other dc nappies been like this. She is always in great form just to add . Does it sound ok ??
If everything else is the same and she is not unwell, it may be worth looking at what you are feeding her. It could be that she is not ready for something. I know my son was allergic to oats. I am not saying an allergy but sometimes their tummies are sensitive so maybe cut it out and then reintroduce to see if that makes a difference.
