I've been getting that too... When I shake it up too. Trying out the the baby Brezza formula mixer to see if get less foam.

I have a Dr. Brown’s pitcher too and have noticed if I put the “blue piece” in the center lower on the rod. (I’m thinking it’s the 2nd or 3rd rung from the bottom) and mix slowly for about 40 seconds then let it sit for a minute or so the foam dissipates. I also spoon the foam out if I’m in a hurry. Even if there is a little foam in the bottles it typically goes away by the time I use them for feedings. Hope this helps!

Hi! Foam is totally safe (and totally normal!), but if you’d like to reduce, we recommend warming the water to approximately 100 degrees Fahrenheit for optimal dissolvability. Feel free to reach to our Sleepless Squad with anymore questions, hello@byheart.com
