I have a formula question. I had used Enfamil for a few weeks until I ran out, then I switched over to Similac since I had a coupon to use...and I noticed that when I shake the bottle up the Similac is really clumpy and doesn't seem to mix/dissolve well. I didn't notice the Enfamil doing that. I usually give him his bottle at room temperature. Have any of you noticed clumpy formula?
