My 5 month old breast fed daughter consistently has liquid bowel movements, she's gaining weight well, are liquid poops distinct from diarrhea?

May not be diarrhea: If a baby is eating, behaving, and growing fine... but has loose poops that can squirt out of her butt, she may be normal, especially if breastfed. Some breastfed babies have loose stools (a bit looser than spaghetti sauce). If she pushes her poop out, it will come out somewhat liquid. If she is very gassy, has smelly poop, or is not growing well, a doctor should evaluate for digestive problems.

Liquid can be normal: Breastfed babies often have liquid stool. They can stool anywhere from a couple times a day to a couple times a week and all this is normal. Once a baby starts some solid food their stool generally becomes slightly more formed, but still remains soft. Diarrhea in babies is often of a different smell, much more more frequent and associated with other symptoms such as tummy upset or vomiting.
