We thawed a bag of frozen BM for the first time tonight (we've been using refrigerated) and there were some thick particles in it, like the fat layer had separated into lots of tiny clumps. We tried mixing it, but there were still some particles of milk in the liquid. We weren't sure if this is normal, so didn't give that bottle to DS. Please let me know if this happens to you. Thanks!
