Hey... Well I've pumped two small bottles of milk (2 oz and 2 1/2 oz). I put them in my bottle warmer and let the temp go up to 145 and set my timer for 1 min. cooled the bottles in ice water and then froze them right away in the medela bottles. How long should I wait to thaw them to see if it worked? If it didn't work does that mean I should let the temp get up to 162 for 15 sec? I've seen others use that method... let me know your experience.
