My husband and I eat a lot of Traditional type foods. We get our (raw, grassfed) milk from a local farmer and make butter and various other things with this, along with drinking the milk, of course.
We are just beginning to slowly introduce solids to our DD and I'm curious if I can stir in some butter or cows milk into her foods, or if this is a no-no at this age.
Yeah, I doubt it would hurt her, especially if it is raw and/or cultured, but human milk is so much better for her. It's certainly not necessary at this stage. Butter though, I think is a good idea. It is a problem sometimes that the solids that are introduced to children are low-fat and low-calorie and replacing high-fat and high-calorie breast milk. Butter would be a great way to get her the extra fat in her solids.
Well, I think if you are using it as a topping or something, yeah, go for it. She doesn't "need" it, but she doesn't "need" any solids, really at all at this stage anyway. My babies LOVED plain yogurt, and they still do! I used it to make baked potatoes more mashable, and very tasty!
