I've tried 2 different soy formulas (for allergy reasons) and they both clump terribly. I've tried every temperature of water, I've tried shaking, stirring, etc & it is still VERY clumpy.
add the formula then the water and shake it dont let it site and us warm water
have u tried putting the powder in the bottle first and then adding the warm water then shaking it if u add the formula last to the water it will clump bad
Add some warm water 1st then your formula & shake well! Or you can try a cheap blender (if it's that clumpy). Or get a whisk or spoon & hand stir rather thank shake.
Lord have I been there done that, and STILL there with my 9 month old. The BEST thing I have ever done was bought a cheap blender! No joke! What you do until you get the hang of it is measure water in the bottle, then pour it into the blender then add the scoops (as directed), mix and presto, NO CLUMPS!!!! Its cheap, easy, and for some reason with my child he liked it better than the all ready prepared kind, or shaking it in a bottle. Also this helps reduce gas if you pre-make bottles!!!
